Billy Kaplan & Rose Hathaway
Billy's magic had been up to snuff during the battle. He'd managed, at least, to throw a few lightning bolts and keep the wolves back from where he was. But there were so many of them, and as time had carried on, he'd found himself flying over the battle, looking to help out those who seemed to be in more trouble than others.
Which was how he'd managed to spot Rose in the first place. He'd landed, hoping to join the fray, when he saw the blood. It was a lot of blood and, under most circumstances, Billy didn't handle the sight of that much blood well at all. However, this was one of his closest friends, and then there was the whole baby... He hadn't even really considered what he was doing, until he'd teleported Rose back to medical. There was no time to consider where they might have ended up, not that it mattered.
He'd desperately wanted to get to medical and that's where he had found himself. But all of that was in the past.
The battle was over now. The mechanisms of recovery were in motion. Knowing that Teddy was alright, Billy had moved down his mental checklist of friends... those he'd known would be in the midst of the fight because they were, after all, his friends.
