This body is not your's to take.
Techablook's voice speaks out from the mouth of his robot. Mettaton desperately tries to fight the other soul out and away but to no avail. Techablook stands firm, not giving in and evenculley Mettaton gives up, returning to his own body. "THIS IS NOT THE LAST YOU SEE OF ME." Mettaton seethes through clamped teeth as he disappears in a puff of smoke. Techablook cocks his head to the side, looking over his new body. He's never been corporeal, so this is new. The smokes subsides. Kit, Tasgore, and Alphys smile at eachother and have a victory hug. "Well done, Alphys! The body looks amazing!" Kit compliments Alphys' work with a thumbs up. As the girls mingle, Techablook tries to adjust to his new body. Taking slow steps so he doesn't fall and embrass himself. The girls stop their mingling when a loud clang, grumbled curses, and shuffling is heard. They look over, seeing Techablook scrambling around on the floor trying to stand and walk correctly but of course, failing.

Kit and Papyrus try to contain their laughter, almost failing when Techablook trips again. 
Tasgore roles her eyes at her adopted sister, kneeling down to Techablook's level and helping the ghost-now-corporeal stand. "Geez, guess we can't call you Techablook anymore." She says gruffly, struggling to hold Techablook's heavy new body alone. Alphys notices this and helps Tasgore carry Techaton up stairs.

Kit is about to follow when she hears the frantic flapping of wings and.. foot steps. Kit follows the sound to the main door of the lab. The sound is much louder now until a loud banging is heard outside, startling Kit. Curiousity chews away at Kit, even though Papyrus advises against it, she opens the door anyway. Just a crack to peer out, but a hand yanks the door open and tumbles inside. "SHUT THE DOOR!! SHUT THE DOOR!!" A recognizable voice shouts frantically. Kit panics and locks the door quickly. "Aerithyn?" She blinks. The winged male is panting heavily, his wings wrapped protectively around something. It takes a moment, but Aerithyn regains his composure, only huffing now. "Hey." He huffs out with a tired grin up at the girl. He sits up properly, opening up his wings to reveal Sans and Frisk. Who quickly climbed out of Aerithyn's grasp and breathed in the much needed oxygen.
"Sans? Frisk? Aeri? What happend out their?"
