Not that I'm an incredibly honest person, just that I don't have the smoothness or discipline necessary to stick to my story like Jackie does. But the most awesome thing about Jackie is Edie Falco, who somehow is able to play this liar-truth-liar-truth thing for every single layer.
Kevin asks if she always knew she'd eventually take it, and it's a sign of their intimacy that he knows to look at her face and go, "Think," before she answers. Later on she'll talk about how Eddie knows her so incredibly well, but I think this is proof that Kevin knows her just as well. She looks him in the eye and says that of course she pretended to consult him, but that he also needs to be honest and admit that he also knew she was doing that. A different kind of manipulation but just as strong.
He swears it never occurred to him, which is a nice line, but given that he's turned every conversation about everything into a conversation about this, all season long, sort of belies that statement. But of course, his denial is confusing too. She gives him a facial response that works like a reward for that, for saying that, like he's earned the right to forgive her. Which will work, because Kevin wants everything to be okay, all the time, which is why she will always win.
"I keep telling you I'm no prize," she says, "And you won't listen!" Which is, for an addict, the most manipulative way to play it, because it's putting the entirety of the responsibility on the other person. But it's answering a question that wasn't asked, because what she hears is an accusation that she's a terrible person -- and therefore untrustworthy, and therefore under suspicion, which means they might start prying into the drugs, which is a problem because then: No drugs -- so if she can beat him to the punch, he has no options but to drop it. What, like he's gonna say "Yeah, but I didn't think you were that terrible." If she says it first, he has to forgive her.
She throws herself on him, and he stares at the wall. "Is that everything?" And when she says it is, he finally hugs her back.
Next morning Jackie's feeling great: All her pieces are back together. Her drugs, her husband, job's okay, she's ready to face the day. Back home, Grace lets him know she was awake when he came home with Eddie, and he promises her it's okay. Fiona finds Jackie's keys in the door -- from last night, when she was in such a hurry to get to the drugs -- and both girls wig out a little bit about how they could have been robbed or attacked. Kevin says he would have protected them, and Grace points out that he wasn't there. "You guys are so smart," he says, because what do you do? It doesn't really chill Grace out too much, but Fiona's easy. He notices the key to the post office box, and gets all suspicious again.
