Sans considers that for a few moments. The way he'd felt before coming over is probably given some context, now.

"Who better to attack your enemy than your other enemy, huh? Hate to admit it, but I'm pretty sure we were the guys there to do Blanche's dirty work for him. Even if it was something we basically wanted to do anyway."

"No offense, but I wouldn't exactly have chosen to show up right then if there hadn't been something driving me to do it. Something about that song of yours must have pushed it over the top."

Not that he hasn't been getting clawed at by the idea that he should return for a while, now, but at least this time it can been in the interest of a rescue instead of so he could turn himself in.
