Prim is a minor side character sadly, she does a lot more in Mockingjay, at least in the books she becomes a medic/nurse and the mother actually tries to do stuff too instead of acting super comatose. The mom kind of ignores both daughters though, I guess losing your hubby and being in poverty isn't a big pick-me-up. But Katniss had the most promise to come back and win, Prim lacks a lot development but she's ok. I like how she's developing in my RP more of course. She's kind of useless otherwise. :/
