No worries. Just voicing a little worry, you hadn't gone too far with it. ;) And tell me what you decide on their past interactions. If necessary, we can discuss it if you wanna come up with a few things Horus had done. We've got time before I can roll out my next post. And even more time before they actually see eachother. And probably... Exchange some friendly gunfire.

Edit: I'll re read Horace's background and whatnot to see what Carter may know. You go ahead and come up with some shenanigans or whatever while they were holding the stadium. Perhaps Horace hated the previous commander, or really liked them and had a differing view of Carter. It's possible, Carter talked to him about focusing his wish to kill on just the enemy. As a special forces operator, he more than likely developed his own desire to spill blood. Though... On a much lesser level than horus.
