Yes, I did get to speak with Bro a little. From what I've been told and understand so far, he probably is indeed the same person, but different personalities due to the circumstances around him. Dirk tends to be very precise with how he types, at least, and Bro doesn't use captialization. I know it isn't a very big difference, but it's one.

[It makes it easy for her to categorize Bro as not Dirk. It wouldn't be fair to be constantly comparing the two when they are clearly in different situations.]
