[Bruce appreciates that Hikaru is willing to listen. He's still not really used to talking about himself or his experiences, and sometimes it shows.]

I lost control on the Helicarrier --sort of a giant aircraft with cloaking capabilities-- and hurt a lot of people, under Loki's influence. But I didn't run away that time. I went to where I knew I was needed, to the team, even in my disoriented state. Losing control like that does a number on my sense of self. But I knew that I had to help people.
