If you don't fix the AC at the gas station in exchange for a box of muffincakes she's basically just a background character. The MC notices everyone forgot about her on the bus and goes to sit next to her to include her in the group and later on at the gas station she ends up sitting on the MC's lap as he's hanging out with everyone else at the back of the gas station talking and she gives him a hug when he starts feeling all sad. That's all the "forced" interactions she has.
Let's compare that to say...Lexa or Annette, one of whom you're forced to break the heart of, or Donnie, who, for some fucking disturbing reason, HAS THE MOST NUDITY IN THE GAME.
Now, I should say that I haven't played the alternate shit yet, but it sounds like that focuses on Samantha and the she and the MC completely miss the fucking bus ride, so I don't even know if they hook back up with the gang.
