Don't forget...

"I'd never forget you dad. I'll find a way to get you back, without killing anyone. I swear.. See you soon.."

- Sans

Don't forget... Is an easter egg animation made by Camila. Since this is a continuation of Yet Darker, this animation is considered canon to Season 1.

Synopsis
Sans is seen entering his workshop and turning on the lights. He walks up to a drawer and pulls out a poorly drawn picture of him and Gaster.

Plot
Sans enters his workshop, opens a drawer, and pulls out a poorly drawn picture of him, Gaster, and a blotted out figure. At the corner of the picture is a taped-on message that reads, "don't forget". Sans tells himself that he would never forget his dad, referring to Gaster, and that he will find a way to bring him back without killing anyone.

Trivia

 * Before being released publicly, this animation was an unlisted video, similar to the scene after the credits of "My Promise".
 * It can be speculated that the blotted out figure is Papyrus.
 * Frisk later wrote the phrase "Don't Forget" on a friendship bracelet they gave to Sans on "My Sunshine", which may be important in the future.
 * This presumably led to Sans remembering Frisk despite his erasure from the timeline.
 * This video confirmed that Gaster is Sans' and Papyrus' father.
