I can def see her getting along with Katie off the field :) They seem like the type of girls who could hang out and throw a few back and joke around :)
Ren likes to know the people in her house so def see her knowing Sophia and Luna. I commented in the Luna intro, but yeah Ren could be a bit weird too sometimes so while I think she would find her housemate a bit offbeat she wouldn't be mean to her.
