So...Bro and I? Got into a strife. Normal stuff, right? But we were on the Astronomy Tower and...things happened.

[He really doesn't want to paint Bro in a bad light, so give him a second or two.]

I almost fell off the tower 'cause he shoved me or something like that. It was my own damn fault for putting myself in that position to begin with. I don't think he realized how close to the edge I was, and frankly neither did I until it was almost too late to say "whoops."
