Outside the party, Doris tells Willie that she wants to show him something in the library, and inexperienced doof that he is (I can relate to that) he seems to think she actually wants to show something. I mean, I suppose she does, but he clearly wasn't expecting it would mean his tongue down her throat.
Back in Tampa, in Nucky's hotel room, McCoy paces and explains to Nucky that he owes Tucker money — it was Tucker's scotch on board when McCoy's ships were seized. Nucky asks why McCoy didn't just tell Nucky he needed money. Because he's not some goddamned charity case, that's why! He wanted to earn it! Nucky's all, "'Earn' it?" Point: Nucky. McCoy says Tucker was going to forgive the debt if Nucky came on board, and Nucky doesn't think that's a good enough reason to partner with "some two-bit fucking hillbilly," even if Tucker's got the locals in his pocket. "The deal is shit, and you know it," says Nucky.
McCoy is all "woe is me" and "I thought you were my friend!" and Nucky says McCoy should have come to him like one, instead of all this bullshit involving train tickets and "stupid coconut drinks." McCoy apologizes, saying he was desperate and made a mistake. "Well, look at you now," says Nucky coldly, refusing to turn from the window. McCoy leaves, and Nucky finds something worth getting upset about: his bottle of liquor is almost empty.
Back on the boardwalk, Roy and Gillian are having ice cream in a restaurant, reveling in their married-couple improv earlier in the evening. Gillian's glowing, and she reaches across the table and takes Roy's hand, and offers him a nickel for his thoughts: "I pay better than most people." Well, it's not the price but what you get for it, right? Roy's thinking they make a pretty swell team.
Gillian gets to enjoy this moment for all of about five seconds before a passing young man recognizes her, and reminds her that they met with his friend Roger about a year ago, outside on the boardwalk. A very confused Roy wants to know what this is about, and Gillian plays dumb, arguing that the man is mistaken, even though he's quite certain it was her. Before he comes round to actually saying anything about Roger being missing or anything, Gillian tells Roy the guy is making her uncomfortable, so Roy orders the kid to "take it on the arches," and oh lord how I LOVE the old-timey slang.
The guy does indeed take it on the arches, and I don't think it's to anyone's surprise that Gillian immediately excuses herself to go to the ladies' room, a perplexed Roy watching her go. Inside, she ties off and shoots up behind a kneecap, bliss immediately washing over her, and when she rejoins Roy she's much more relaxed. So relaxed she doesn't appear to be quite all there. He asks if she's OK, and she says she is… and then she realizes she's been gone so long her ice cream melted. Well, when you've been in the bathroom long enough, there's really no good explanation that anyone wants to know.
