[Agent Z]

Lamont was fun, althougth i can't say i miss him, still very considerate of Peter in keeping his word lol.

As for Carlie, i kind of quit on her once Felicia told Peter that he should go for her like...really?, does that sound like something that Felcia would do?. Plus the trying to tatoo a goblin on her to spite Peter, granted she was drunk but it was still weird.

I can see Felicia doing that. She was written as not wanting to be permanently attached to Peter at the time, so she wouldn't care who he's dating. The only one of Peter's love interests she's ever expressed dislike for was MJ and that's because MJ is the only one, save for Gwen who is dead, who can actually compete with her for Peter.
