The dog lets go, and Chara can drop the tinsel - only for it to turn and attack its owner.

(If there's something in Chara that's rooting for the dog, it's quickly snuffed out. That's not a nice thing to think, Chara.)

The dog tinsels off into the horizon, and Chara walks over to the fallen kid with a certain not-looking-forward-to-this reluctance.

"I am sorry," Chara tells the stunned kid, head ducked, attempt at smile on. They give a small, stiff laugh, rubbing the wound in circles with a thumb. "I must have provoked it."

They dither, just a bit, and then thrust out the non-bitten hand towards them, somewhat hoping they don't take the implicit offer.
