Julius doesn't, though he does slow enough that Isaac can catch him up if he tries. There's a sense of something off, with Isaac there; something he can't quite put his finger on. But that sense of offness doesn't prevent him from engaging. "What is it?" isn't unfriendly, but it has the briskness of someone in the middle of something.

With luck, no one is going to ask what that something is. Julius is relatively senior (for all he hasn't snagged that word in his title) and known to be level-headed. With luck, it might be enough.
