Bad Sam is applying false eyelashes in the bathroom while Todd stands in the door and acts like a big girl, asking Sam if they live together. She tells him they don't, because even though he has a drawer and a third of the closet, he's not paying half the mortgage. Todd agrees that's never happening, but he does ask if it's okay if he keeps hanging out and sleeping in her bed every night. Sam: "If you stopped, I'd kill you." Todd: "I love you, too." Bad Sam gives him a not entirely Bad look.
Good (drunk) Sam is wondering if she might have never told Todd she loved him.
Cut to Sam standing outside the door of Todd's apartment, screaming his name. He throws open the door, and she asks him, "Did I ever tell you that I loved you?" It turns out she didn't, although she did leave malicious graffiti to that effect on his car. Sam tells him that she wants him to know that she did love him, and she wants to pretend that it's the past so that she can tell him that she loves him. "Then. Not now." And with that, she wanders away. Todd goes back into his apartment, where his poker buddies all make fun of Sam for her declaration (which they overheard). Todd, clearly hurt, tells them to shut up.
Sam walks out of the building and tells Frank that she expressed the hell out of her love. She's decided that, from now on, she'll only tell guys she loves them after she doesn't actually love them anymore. That sounds a lot better than my plan of telling guys I love them before I've even met them. Sam is about to make an exception to her policy of only telling men she loves them until after she doesn't by telling Frank...something. But he shuts her the hell up before she embarrasses us all.
Sam exits the elevator at work, while her V.O. tells us that love is a battlefield and hell is for children and we belong, etc., etc. The trick is finding the balance between being dead inside and being too open. And then Sam proceeds to yell at Tracy for slacking off and not doing her job. As Sam walks into her office, she almost looks resigned to being Bad Sam. And then she runs back to Tracy and tells her that she meant to yell at her with a "please" and a "thank you." Which is really all any abused underling can hope for.
