SPOILER
Dupree does seem disturbed by the Jeeves/Lance hookup, and he did have a flashback to Jeeves removing his shirt.
Maybe he'll try to get it on with Nick, but with thoughts of Jeeves running through his head, and will interupt proceedings just as Lance and Jeeves are about to get it on.
However, as I've stated on other threads my speculation is always miles out.
Always
Meanwhile at Casa del Cantrell/Del Mar they are tucked up in bed with their cocoa.
