Eponine will be having a blast, flirting with everyone, wandering and getting to know what's going down. She'll mostly be at the festival, somehow finding a way in without paying, if at all possible.

Elizabeth will likely be leading Booker around, exploring and enjoying life. She wants to dance. Everyone dance with her.

Layla will be missing Jamie, but what else is new? She'll also be exploring, really seeing what there is to see. Also detectiving.
