C'mon, why don't we go out today, yeah? It's been awhile... We should go out.

Dust smiles slightly at you as he spoke. After killing you, he started to lose his sanity, telling himself that you weren't actually dead. After so long of you being gone, he started to believe himself. You were always there and he was pleased with that since he was alone constantly and all he wanted was you. He never meant to kill you, but he was spiraling out of control... Now, all he did was spend time with you.
