Sans isn't a very strong guy, so wrenching the guitar away from him physically probably isn't much of a problem. If he's anything, though, it's quick. He sees the tree attack coming and pops himself up into the air with a burst of blue magic, before shortcutting to the back of the stage and behind Greg's back.

He's not exactly sure what Luce and the Doc are trying to accomplish but sure, why the hell not, he'll just keep doing his thing over here - even though he's sure, with a growing sense of dread, that he must only be seconds from destruction. Blanche already feels later to the punch than he has to be.

His focus catches on the golden gem hanging above them, though - not totally dissimilar from the one he'd held between his hands days before. The one that he knew contained an entire soul. For a few fractions of a moment, he has the chance to think about what he's seeing - Greg and Meril, two stones hanging above them - a song that seems to suck him in...

He comes back to reality with a jolt, concepts aligning in his head as the fire in his left eye socket starts to truly burn. He jumps again, trying to grab the stone into a spacial pocket, or to drag it down with a shift in gravity. Even as he begins working his magic, however, he can already feel a power rising up to resist him.
