"It's just up here," he says through the rain, and turns into a side alley. It's a little more shielded from the rain here, the buildings on each side and stuff overhead blocking out a lot of it, but unfortunately also shielded from the view of the general public.

Which is probably the exact thoughts of the guy who'd been skulking around there, and as they pass, suddenly shoves Seth into Daniel, then takes advantage of them being unbalanced to snatch one of Daniel's cases right from his hands and take off down the street.

It probably says something about how used to this kind of stuff Seth is that he has the instincts to immadiately push himself upright and bolt down after the guy. In normal circumstances Seth night not have been able to catch up so easily, but that bag must be pretty inconvenient to run with, so even with him having a late start, it's only a short intense sprint before Seth manages to grab the back of the guy's jacket and pull him to a sort of stop.

He throws a punch that doesn't quite connect, but is still enough to make the mugger reconsider and drop the bag, before wrenching himself free and running away. At this point Seth is more concerned about Daniel's possessions than he is about giving the guy a solid banging, so he stops for a moment to catch his breath, then stoops to pick up the bag and heads back to return it to its proper owner.
