Another sketch Undertale commission. Commissioners AU.

Gaster is finally back at Snowdin after a long rehab. His right eye is blind after an accident at the Core, but Gaster's still determined. Papyrus believes that Gaster can undoubtedly fix the Core. Sans is worried, but, nevertheless, hopes for the best. Nobody knows that the second accident will bring on Gaster's death. P.S. In this AU Gaster is the elder brother of Sans & Papyrus.
