We zip from the glowerers to the brooders as Mark thanks Demetri for "backing my play." Demetri would like to know which play he's backing, please? "Is this about taking Tattoo Man off the streets, or putting him under it? ... I know you said if we get this guy, we might be able to change our futures. I wanted to make sure here the plan wasn't to kill him so he can't kill me or come after you in your office." Mark pissily inqures, "Whatever gave you that idea?" Demetri points out that Mark isn't the only one invested in making sure the future doesn't come true. Mark is all, Oh, yeah, you're a little hung up on missing St. Patrick's Day 2010. He tries to glare self-righteously at Demetri -- and fails, as those big, Bambi-esque eyes simply can't summon anything more scalding than "mild confusion" -- and asks if Demetri really thinks Mark's capable of killing someone on the suspicion that it will prevent an unwanted future. Demetri replies, "I would've," and walks out. Mark sits there and tries to look darkly contemplative but again, the Bambi Mug pretty much makes it look like he just smelled a flower that didn't live up to his olfactory expectations.
Janis, meanwhile, is busy reading up on sperm donation via Wikipedia, because why wouldn't you trust anonymous, crowd-sourced and self-vetted information over any content produced by accountable medical professionals? Wedeck comes up to ask what she's doing, and Janis replies, "Trusting my gut." And, probably, dying a little on the inside now that her boss has seen her browser with the words "SPERM DONATION" splashed across it in 48-point type. Wedeck rubs her shoulders with paternal affection (aww!) and prods Janis about a prior email.
Janis has a new, NSA-provided rendering of the Suspect Zero photo, and the only interesting and useful new thing to come out of it is the observation that Suspect Zero is wearing a ring. Wedeck would like the NSA to work more digital wizardry and identify the ring ASAP: "If we can tie this jewelry to the guy wearing it, we'll have our first workable lead."
Mark comes home to Surly Benford Manor and interrupts Olivia mid-laundry folding and tells her, "I killed a man today. I had a shot at changing my future -- at changing our future, and I took it." There is the requisite post-murder hugging and Mark tells Olivia, "Maybe April 29 is just going to be another day at the office now." A troubled-looking Olivia's all, "Come again?" and Mark unravels the logic: since he's killed the man with the star tattoos, surely he's changed the future. Because, after all, nobody in the history of the world has ever gotten the same tattoo as anyone else, right? As Olivia hugs him, she realizes Mark's just one-upped her in the future-changing efforts: it's a long way from tossing lingerie to killing a tattooed goon.
