Rachel says she doesn't know how to do this alone, and Olivia comforts her by saying, "Ella is beautiful, and smart, and strong, and she gets that from you." Rachel says Olivia's the strong one: "I've only done one thing right in my life." By which I hope she means Ella, and not, like, "I finally solved my Rubik's cube." Olivia tells her she needs to be strong for Ella. "Whatever you need, I'm here. And you guys can stay here as long as you want." Rachel thanks her, and Olivia gives her a look: "Is there something else? Something you're not telling me?" Rachel says there isn't, and gives her sister a kiss on the cheek. Naturally, there is something else, but we're not going to find out this episode.
Olivia's at her desk at Boston Federal Building the next day when Loeb strolls up. "How goes it?" he asks. "Horrible," says Olivia, and thankfully that's all she says, like how annoying are co-workers who don't understand that "how are you?" is really just a pleasantry and not an invitation to tell me about how your husband's boss is being a total douche lately, for example? Loeb tells her, "We'll find 'em," feeling it necessary to add, "whoever's responsible for what happened." He picks up her eight ball and jokes, "Maybe this'll help," and tosses it to her, only she drops it and bends over to pick it up, which is where she notices his black loafers, identical to the ones worn by the dude in the mask. She straightens back up, looking very wary of Mitchell, who doesn't notice it at all. I, however, would love to play poker with Olivia, who looks like Mitch just suggested they go out to lunch and eat some babies.
She goes over to Charlie and quietly tells him she needs to talk to him. Out in a corridor, she says, "I think I know who killed Simon. And I think it's the same person who abducted me." Charlie asks her who. "Mitchell Loeb. Don't ask me how I know. I'll tell you later." Charlie does not say, "No, you'll tell me now why you think a fellow agent kidnapped you and killed someone." Lucky for her, because all she's got right now is frigging LOAFERS. He does express skepticism, though, and she says she can prove it: "But I've got Harris watching me like a prison guard. I can't do this myself." Charlie asks her what she needs. She needs to prove it to him, is what she needs.
Olivia pulls up at the Loeb house, easily identifiable by the huge "LOEB RESIDENCE" sign on the lawn. She rings the doorbell, but there's no answer, so she walks around the side, peeking in the windows.
