oh ren can help her find new junk food. it's a staple. or old junk food. there's probably a black market for retro candy and ren's the girl to find it if there is.
it's pretty basic, but i think it'd be fun if thea was wandering around in a culture shocked stupor and got overwhelmed and tucked herself away into a corner somewhere, only ren's already there, creeping on people and data mining or whatever she does. weird conversation happens, ren's like yo, i got you, and talks her into coming aboard.
