Eleanor totally commented on your dreamy eyes again, Margo. (And she's waiting for her to change back so she can realize that Margo always has dreamy, soulful eyes.)
Jake totally checked in then, disappearing after her for a little bit. He's not sure what's going on, but he's not going to press too much because he's still being cautious. Though at this point, he's more back to himself, nudging her with his elbow, letting her know he's there, stealing a forkful of cake from her, and then he will go join the orgy.
(And he may ask if this ripped male form of hers enjoys running anymore than her normal self...)
