Okay, no. Not this time, Lapis. Sans is just about done with this shit.

Though just barely capable of focusing, he's on point enough to realize that he is probably about to be attacked - so when that wave comes, he's actually capable of short cutting out of the way. He appears a foot or so above the ground on the other side of the wave, hanging in the air with the help of a bit more blue magic.

He tries to grab Lapis in his gravity field again, hoping to hurl he back into the trees - and away from Frisk, more importantly.
