That's why he didn't try this sooner, say, before Gaster came at him with a vial of deadly, experimental nastiness. Without a hand, it would have been pretty difficult to get both arms and legs reattached before they turned to dust and he lost them for good. Then, he'd be able to use the hand to reattach everything once he was free. That way, the teleport would yank it out of the restraint, instead of dislocating his elbow.

The compromise was to separate his arm and legs at a relatively weak joint (knees are less complicated than hips and ankles, elbows are less complicated than wrists and about as complicated as shoulders) so that the teleport could complete itself.īut first, he had to get his hand pretty close to being out of the wrist restraint. The table is bolted to the floor, and the teleport isn't strong enough to either break the bolts or move the entire room to another location. Sans teleporting away from the table forced his magic to fight with itself. Once the limb is completely dislocated, it goes numb, and would turn to dust in a matter of minutes if not reattached. Pulling an arm or leg (or two or three) apart at the joint doesn't feel all that great, kind of the same way that you'd feel if you dislocated your elbow or knee. Sans' bones are held together by the same magic that's keeping him alive. On the other hand, something just touching him wouldn't necessarily be pulled along for the ride, say, if he was balancing the watch on top of his head instead of wearing it. It's not something that he can consciously control - if he happened to be wearing a watch, he wouldn't be able to teleport off somewhere and decide to leave it behind. That includes his clothes, shoes, anything he's holding on to, and so on. Sans' teleports work on Sans, and whatever happens to be attached to him at the time. Ooooh boy, this one needs a bit of explaining.
