"Peter Parker is just in a different place in his life. It's wearing on him, being Spider-Man and not having a life of his own. I always thought it was peculiar to me how this kid couldn't see how he could just have a little balance in his life and things would be a little better for him. But there are complications to that, which I understand. He doesn't want to put his loved ones in danger and also, just being honest with people at first causes him pain. Just being around Aunt May at first is a painful experience because he's constantly wracked with guilt and feelings of responsibility for all the bad things that happened. He faced that situation and it helped their relationship. It helped set him free in their relationship. So I think that stuff is just wearing on him. He wants a life of his own. He wants to have some kind of balance in his life, but he also has these gifts and wants to use them responsibly."
