He knew there was a risk, and when she repeated what he was thinking it made sense that maybe it wasn't the way to handle the issue. "Maybe just to cope with it then. I don't wanna forget anything more than I already have." Which was true. When the last seven years of memory was spent being someone you weren't, he couldn't risk losing some of the things he wanted to keep.
He was a little blunt with Emma, but it was mainly because she was the first person he had found that didn't act like it was a miracle he survived. Maybe that was because of limited interaction before he went missing, but he was glad that someone didn't hug him and cry when they saw him. It was nice to know they missed him, but it was a little much to take in on the first day.
"Things that don't fit in with who I am." He had a flash of blasting down a wall to a grocery store. When cops arrived, he used a low level blast to knock them away. He clung to the idea that he didn't kill them, but it wasn't enough. "Not the person I was taught to be while I was here." Another memory of using hand-to-hand training to beat a man. The guy was trying to protect his family, but Scott needed building supplies. At the time, he was confused, because he didn't know where he learned to do it. Now he knew it was at Xavier's. "Things I'm not proud of. And also memories of...Jean."
It wasn't that he wanted to forget Jean. Not exactly. It was just his knowledge of her dying twice now. Once was enough, but knowing she died a second time while he was gone was a little much. If he had known, maybe he would have hoped his memory stayed gone. As much as he was glad to be back, and know who he was and what purpose he had...it was easier when he thought he was 'Erik' and surviving anyway he could.
"I don't know. Guess it was a leap of faith, right? Get the telepath to erase everything." He laughed only a little. Scott was an odd person now. Deep inside, he was who he had always been. But now there were hints of gray mixed in. He wasn't sure what he was anymore. "Thanks, Emma. Sorry for bothering." With that, he turned about to leave. Maybe it would be better to deal with it on his own.
