The Duke tries to get everyone in the tower to get back into RP. Unsurprisingly, Greg does a good job, Letty puts in effort, Tai is Tai, and Creature refuses to say anything. Oddbod is also there, likewise doing nothing. Fattius comes up (keeping RP, as always). The Duke gloats, saying that they have only collected two artifacts and are thus almost certain to lose in the final battle. He tries to get Tai to leave the Tower to help find relics to give the party a better a chance. He refuses, for the time being, but says he won't shit on camera and he'll take one for the team and leave if it comes to that.
Xavier
is expected to arrive soon (Sam asked for an ETA). shows up and the Duke warns the party not to listen to Xavier's bargain. He challenges Letty to a YuGiOh duel. If she wins, she gets (another? the final?) Exodia card. If she loses, her fate is sealed. She accepts.
Also, Xavier's girlfriend shows up. He says she @'ed him on Twitter. I don't think she's someone we've seen before but she's wearing a mask so I could be wrong.

He is now immune to the dark arts of homosexuality.
Edit: Actually they dueled the Black Market Trader as a miniboss. Jimmy and Letty played together and won in the end. They receive the Exodia card but there is one more out there. The Final Card is also one of the Five Relics. Letty asks whether that card and the Staff of Worms will be enough to defeat the Duke. Xavier reveals that he stole the Staff during their retarded heist. They'll never get it from him, he says, so they're screwed.
Xavier explains that his GF is proof that, though he may seem like a misogynist, his admiration for Xavia is proof that he is, in fact, a feminist. Letty retorts that being nice to women doesn't count if the woman is trans. lol
