...so we head down to the infirmary, in which Boyd and Whiskey are playing out the scene from "Epitaph One" in which she desperately tries to get him not to go. As touching and well-acted as it is, since there have been no changes made to it I see no need to recap it again...

...so let's move back to Bennett and Topher. Ivy tells the latter she's going to go in the back for some work-related reason, and Topher doesn't hear her, really, so wrapped up in Bennett is he. He dreamily comments on her work, and she smiles in enjoyment before sending him off for some tool she needs. He starts to leave, but comes back and plants one on her. When he pulls away, it seems like she bit his lip instinctively, for which she apologizes, and then he keeps kissing her and she keeps biting and apologizing, which is funnier in execution than I would have expected. Also: Aw! Topher suggests they do more of that once they prevent the end of the world, to which Bennett agrees, and he then confesses that he had a crush on her even when he thought she was male. He starts to leave again, but once more turns back: "This is better." Heh. When he's gone, Bennett takes a moment to process what just happened, and then starts to get back to work -- but Whiskey's voice interrupts as she says Topher's in love with her. She adds that she used to be Number One, and something is palpably off about her here but it could be attributed to her grief over Boyd leaving, particularly against the backdrop of Topher's and Bennett's newfound happiness, so it's nice misdirection for what actually happens. Once she confirms that Bennett is working on Caroline, she asks if she thinks she'll succeed in restoring her, and Bennett replies that she's confident of it. She, in turn, asks if Whiskey really thinks Topher likes her, and Whiskey points out she didn't say he merely likes her. Bennett thinks he's remarkable, but Whiskey tells her she didn't think he was even capable of acknowledging the existence of another human being, let alone loving one. "I think you're the remarkable one." And with that, just as Topher returns, she DRAWS A GUN AND BLOWS THE SMILING BENNETT'S BRAINS OUT! I mean, you sensed something was going to happen here, and Whiskey was kind of being too protective of her arms, but that was still shocking, particularly given that Bennett's blood ends up spattered all over poor Topher's shirt. Hmm, probably shouldn't have mentioned that. And sorry to see you go, Summer Glau, but take heart in that you were totally awesome, as usual but particularly in this episode. Whiskey fixes Topher with a despising look and heads out of the lab and straight into the last commercial break.
