Well, aside from the perpetual peppiness that her premade mentions, Rachel's the sort of person that's fairly book smart but lacking a bit in the common sense area, so despite having a geeky side to her, she's constantly trying to prove that she's not a complete ditz. If that makes any sense, aha. Anywho, she tries to make friends with people whenever possible, so I suppose how they feel towards each other would really depend on if your character could take her seriously.
