Gwen is intelligent and quick-witted with a tendency to be sarcastic. She tries to put up walls to prevent people from getting close to her out of fear of losing them like her friend Peter. While she tries to keep people at bay, when she does let them in she becomes incredibly emotionally attached to them to the point of her keeping the accidentally undercut that she had gotten as a result of Miles's hand getting stuck in her hair due to her missing Miles after leaving his universe.

"You put on that badge because you know if you don’t, someone who shouldn’t will. But you have to understand, this mask is my badge, and I'm trying to be good too. I was trying so hard to wear this thing the way you would want, and I didn't... I didn't. I can do all these things, but I can't help the people I love the most, and they can only know half of who I am, so I-I'm completely on my own, and now I don't even know what the right thing is anymore! I don't now what I'm supposed to do, but I know... I can't lose one more friend."
