Sans would love to be able to take off right now - these demons can probably fly, too, but he bets he can fly faster. Unfortunately, the second he lifts into the air, the demon jerks him back down to the ground again with that chain, and the sensation only proves to further rattle Sans's mind. It feels like what had been done to him before - a dark power, binding his ability to escape.

It's enough to cause him some panic, and where it not for Iuliael smothering the other demon in his wings, they probably would have had the chance to get in a blow strong enough to take Sans out. However, it's the sight of that strange, broken angel fighting that helps Sans get his head back together.

He darts around the side of the demon, using his own chain to trip him up, dashing around him more quickly than the demon can untangle himself. Despite the other end of the weapon tearing into Sans's wing and scattering golden blood, he still manages to lift himself into the air - just enough to drive his scythe through the demon caught in the middle.

Blood splatters, and he's not certain that the demon is finished for good - but he has other things he needs to worry about. Shaking his wing, but still unable to dislodge himself from the corpse he's chained to, he calls out to Iuliael:

"Let go and get back!"
