I swore to myself that if my idiot brother ever needed backup again I would sprint the other way.
Not knowing he needed backup was no excuse. There was no way I would rush to save him again if he wasn't even going to appreciate it, and actually attack me in the process. Even if he didn't actually know it was me. And, okay, I admit that I may have seemed like a menacing bad guy. But still, no excuse.
We were going to have to have a serious talk about using magic to throw me through walls.
