I feel that Dolly will help remind Kara to relax every now and then - she seems really laid back and I think that’s going to be important for Kara moving forward becoming a superhero and fighting crime - that type of life can weigh heavily on anyone.
I think it’s interesting to note both of her friends, Dolly and Jen - you have Dolly who is more lax and Jen who is kind of the opposite of that. Did anyone else notice this? I think it might help Kara find her path being in the middle and having a bit more of a moderate personality.
