alan: you know what the best part about being a student is? if i don't pass a reflective surface, i'm convinced that i'm 25 years old and i'm, uh, about to conquer the world. well, i surrendered all my dreams of conquest when i realized all i'd have to show for it is... the world. hey, hey, larry, what's eating you? a particularly repugnant woman who somehow manages to link all science with hitler and the devil. oh, come on, larry. it's not worth getting upset about every crazy out there. i know this! i live in a monastery, i meditate. i-i believe in peace and, and compassion and tolerance, but still this woman, she triggered such outrage in me. i think that people like that, like this woman, they're just looking for something-- they're looking for answers, you know, maybe even some of the answers that you are, but just by, uh, different means. you cannot begin to justify this woman's spewing of her venom. n-n-n-no, i'm not, i'm not. it's just that, um, not everyone has the emotional and intellectual resource to search for god in a supercollider. people look for answers in what's available to them, and when they're particularly desperate, they latch on to the closest answer that's available. i mean, it may make them wrong but not necessarily evil. yeah. listen, i know you're right. all my life i have attempted to find just that perfect point of beauty and balance between science and spirituality, where they not only coexist, they complete each other. and i saw in this woman's... rage and her ignorance a complete caricature of my faith, and yes, i did match her bigotry with my own. god will rain his justice on your heads. i can live with that, mrs. doran. you're a faithless charlatan! you've spit on everything we sacrificed our lives for! you can't hide in the church! he will find you there! we're positive for arsenic residue in the laundry room. okay, how conclusive is this? heavy concentrations. we're going to find it all through the house. why would anyone want to harm us? it's indicative of someone mixing water and arsenic in a container, not someone trying to kill you. are... are you accusing me? actually, mrs. doran, i am arresting you. please... this is your test. i can see that now. let me be strong enough... (screaming): hurry! audrey! hold on, i'm going to get you out of there-- back up! craig, give me your hand. you okay? can you walk? (panting) (coughing) (grunting) (coughing) father-- in the kitchen.

(siren wailing) hey, so, anyone else? just reverend ezra. craig ezra, audrey doran, they were shaken up a bit, but they're going to be just fine. and you guys are all right? yeah, i was going to wait for the fire department to get here, but granger made me look bad by running in there. ah, heroes. right, the reluctant hero. hey, at least you got to carry a girl. so any idea what caused it? no, we don't know yet, but the kitchen's hot for arsenic dust. it was clear yesterday. susan doran? she was cuffed and in our custody. but she could've set a trap. well, maybe a kid. craig says he and audrey were here to meet with his dad. their alibi for the coffee poisoning is weak. i mean, the hotel has them checking in and out, but it doesn't mean they were there. david: so what do you think? kill dad, put mom in jail, then they get married, take over the church, but that'd mean he drank his own poison and he sat on his own bomb. right, so it makes him stupid or a hardcore. larry (over radio): you know, it's really your dad's insight that led to the epiphany re: my egregious behavior. goggles. larry: okay. version 17... (motor running) no reaction. let's try intentional ignition. all right, where was i, by the way? uh, "epiphany" and, uh... oh, yeah, yeah, yeah... "egregious behavior." there i was, i mean, so self-righteously attacking susan doran but never realizing that i was just projecting my doubts onto her. doubts about, uh... about what? well, about my faith, you know. i have to wonder, all these questions i'm asking-- are they an expression of my belief, or are they just a failure to surrender myself to it? larry, does it have to be an "either-or"? hey, there's one to grapple with. larry: you know, the monks say there are no enemies, just the unresolved within us. hey. hey, so... so we think heat accelerated arsenic dust to create this fire. there was a similar dust explosion at a sugar factory in georgia. wasn't that an accident? larry: set off by sparking heavy machinery. yeah. we've been attempting to recreate the accidental combustion all morning, using kitchen appliances, but nothing's exploded yet. yeah, but that won't explain what the arsenic was doing there in the first place. which is why our next test will be to determine if the explosion occurred by design. (switch clicks) whew! uh, confidence is high this wasn't an accident. what does that do to your network analysis? well, network analysis was an analytic sledgehammer. with the additional murder, we've graduated to a scalpel-- affinity analysis. beer and diapers. oh, it's a classic story, most likely apocryphal, all about a grocery store that wanted to know what items sold most often with diapers. they discovered it was beer. now, from this they inferred that the wives had delegated the diaper-buying to their husbands, who consolidated this duty into their weekend beer runs. they started stocking the diapers next to the beer coolers, and increased their sales. so, using affinity analysis and association rule mining, we determined that this crime must have been committed by a partnership. so we reexamined the relationships and behaviors of, of your varied suspects and it keeps leading us back to audrey. megan: susan's daughter?! okay, so charlie says to reinterview the suspects. i think i could have told you that. but audrey is the one with no motive. not if she's helping her boyfriend. or her mother. i see the thinking. i say she's a wedge. that's our only move. thanks, peter. oh, and don? quit browbeating my assistant for personal information on me. you gave me up? i know where my paycheck comes from. aha. now, what makes you think that he would have something juicy on me? i'm thorough. oh, yeah? what do ya got? we'll see. i'm still compiling. nothing. you got nothing, eppes. and what about the hotel? was audrey there with you the whole time? no. not the whole time. she left for an hour for dawn prayers with her mother, but she came right back. so she had time to poison the coffee? audrey? colby: she was the only one who didn't have an alibi for all three of the crimes-- the fire, the poisonings and the death of your father. but she handed me the coffee. the morning of the poisonings? yeah, first thing. i mean... she poured me a cup. right. but she didn't have any herself? no. oh, god... what? well, before the church exploded, she called us over, father and me. audrey's the only person in the entire church who doesn't have an alibi for all three of the incidents. why would she need an alibi? because we have a statement implicating her in the poisoning. what? megan: your daughter set you up, susan. she killed your husband. is she working with craig? no. is she working with you? i know i am being tested. we found arsenic all over your house. if it wasn't you, it was audrey. she had nothing to do with it. i did it. i did it all. what did you do? poisoned the coffee. poisoned my husband. huh. this is wrong. she's the wrong person. it's not the outcome we expected, but they've got their confession. you know something? i think you need to arrest craig ezra. well, how you figure that? what we may have here is the test of solomon. now, if so, susan doran just now sacrificed herself for her daughter. okay? you tried to cut her baby in half. she wouldn't let you, no matter how much the cost to herself. and then craig fed her to the wolves. larry: that's it. charlie: however, it's pretty counter-intuitive that he would put himself in harm's way twice. and still he survives. hold on. a bible story's not gonna trump a confession. no, i mean, obviously, with real stories of faith, you know, they don't have easy answers, but this story does give us a place to find them. all right, you know what? given the results of the interviews, why don't... why don't you give us some time to revisit our affinity analysis? all right, good. go for it. charlie: all right, so, well, this isn't working. craig-slash-audrey and craig-slash-susan have low support values. craig alone has a low predictive value. i'm thinking we circle back, try a k-optimal pattern discovery. charles... what are we missing here? aside from a positive result? reverend ezra. i'm put in mind of one abimelech, who slays his clan in order to rule his family and his kingdom. slay your clan, poison your church. after murdering his own people, god condemns and kills abimelech, but not for his sins against his people. no, it was for dishonoring his father, gideon... who was already dead. wow. i really don't understand the bible. well, the point i'm making here is that a father's influence over his son can define him, and maybe even drive him. so ezra-... slash-craig. that's a relationship we haven't been focusing on. david: before 1998, a joseph and emily ezra lived in bangor, maine, they went to work, went to school, they paid taxes... and then... nothing. (typing) now, between 1998 and 2005, the ezras did not exist. no credit cards, no drivers' license, no taxes-- nada. then joseph and craig ezra showed up at patmos. so what happened in 1998? i think the real joseph and emily ezra, they died. a car crash. the bodies were burned beyond recognition, no match to dental records, the identities went unknown. 1998. portland, maine. i know you got more than this. yes, i do. before the ezras went missing... they had a foster child. megan: that would be craig. craig? hey, craig, we're gonna need to speak to you for a second. what for? just want to talk to you. about audrey? me? colby! (clattering) (engine starting) (tires screeching) this is eppes. you need to run california plates: four, david, ocean, queen, six, seven, eight. you all right, colb? yeah. yeah.

(remote clicks) meagan: if it wasn't you, it was audrey. susan: she had nothing to do with it. i did it. i did it all. you did what? poisoned the coffee. poisoned my husband.

(chuckles) no, look, i-i try to remember the job's more important than me. well, we all pray at our own unique altars, don't we? well... you know, i think of religion as a... a really good police force, you know? it keeps 90% of the people honest and then we worry about the other ten. that's religion. how about belief? well, look, you know we weren't a big "god house." i just always figured one exists, but... that's pretty much the extent of it. pascal's wager. one lives as if god exists. if he does, your gain is infinite. if he doesn't, well, you've lost nothing. think vegas gives odds on that? (wry laugh) you don't feel any... any emptiness in this? ah, well, hence the alcohol. well... they let my mom go an hour ago. i think they're going to arrest me. craig (on phone): the church has been tainted by outsiders. we have to rebuild it. how? we need the money. it's the right thing to do. i mean, you know the combination. to start again, we need a lot. as much as you can take. okay. okay, yes. where should i meet you? union station in an hour, main entrance. audrey, i love you. i love you, too. all right, there he is. we moving in? no, let him take the bag. what if he wants to take her with him? don't worry, not this guy. i wasn't sure. i didn't think think you were going to make it. how much did you get? i don't know, a lot. okay, look, go back to patmos, and, um... i'll call you as soon as i find a safe place. craig... trust me, audrey. this is for the best. bitch! move! audrey, come with me. not sure where you're going, buddy. david: i'm pretty sure the top of this tower doesn't come out in mexico. clear the bottom! clear the bottom! david: come on, craig! we know who you really are. you're not the jumping type! colby: freeze! don: don't move! take it easy. nice and easy. that's it.
