Dream befriends Killer Sans //Driller//

Dream tries to build a relationship with Killer, who has a crush on him but doesn't show, because he doesn't want Nightmare to think he is a traitor and because he can't really feel emotions unless his pupil in his eye socket turns white.

Nightmare and his gang knows about Killer's crush but doesn't think that Killer can get in the relationship because the Star Sanses are their enemies. But a little spy name Swap who is working for Nightmare in this Multiverse, tells Nightmare that he saw Killer with Dream in Dreamtale and Nightmare goes to take a look at this for himself.
