Deimos founded Black finger less gloves, when he tried it on, Black flames appeared on his back and head. He can spawn Christor because Jeff's finger-less glove powers were transported. With Hank, he used his footsteps to distract Jeff. Deimos saw him and finally got the chance to remove his skull cap and kill him and.....He killed Jeff for once. Sanford still had the Sp4wnHol3 D3v1ce on his hand and is still on the Dissenter's base.

Jeff will come back later, just without the top of his head

You mean, SOMEONE will revive Jeff? (Also without the top of his head he wouldn't have a brain so nope)
