Coulson just shrugs, because while it wasn't fun at the time, it's over with and now he knows to be more wary and vigilant. Not that he wasn't before, but now he knows a little about what kinds of things can happen around here. Sure, there's not much he can do to prepare, but at least now he knows that ignoring phone calls and mysterious knocking are rarely good things in this town.

"Hey, it was a lesson learned. I might not like what happened, but at least now I'm more aware of the dangers than I was before." He sighs, but it's not as deep as it would be normally, courtesy of his run-in with the mirrors. "I'm not sure I'd call it trouble, exactly, but there's definitely some shortness of breath going on. I don't think it's serious."

He doesn't mean to downplay it, but it doesn't seem to be life-threatening, although he's not a doctor and that's only his opinion.
