jesper fahey: 19, from grishaverse, is a sassy sharpshooting thief who is also grisha ... so he has ~special abilities~, basically. he's a hot mess, but he means well. he's closest in age to hope, lissa, alex -- depending on if any of them attend community college or something, they might get to know him that way! if they're willing to have a dubiously-moral thief/liar/gambler in their lives, lol
kili: from the hobbit movies! kili is the same reckless, loyal, optimistic lil dwarf that he always was! he'll talk to ANYONe and he's going to really enjoy being in this world and learning all about it.
sam wilson: from the mcu. he'll arrive right off of falcon and the winter soldier. and i would LOVE to see him play off of the DC characters, i am really looking forward to that! i haven't watched a ton of supergirl but i really liked it, so i'll definitely throw sam at kara. sam would probably get along with veronica, too!
