If sans fell in core instead gaster 

This is a good starter for an au. Imagine frisk coming down and gaster is the judge as well as the royal scientist. Imagine his pain when pap dies and then he's lost both kids.

Few years later.. Frisk fell.. They were immediately illiminated because -Sans- wasn't there to help..

I feel so bad for Gaster. He looks so upset..

Time to cry to sleep tonight

Can you maybe have the Aus react to this?

Bruh.Who else noticed that his tears are blue and orange?

Bewear the man who speaks in puns.

NOOO SANS!!!! *me sees someone crying*

So sad, make part 2, i wanna this being story pls

This should be an AU

I have a theory on gaster's Magic coming from sans (blue magic) and papyrus (orange magic) so that gaster soule be unable to cry blue tears because of sans death

Whh couldn't sans just teleport away from the bomb

I am crying to sleep tonight

Can I do a part 2

Few years later... cAn I hAvE tHiS hOoDiE (sad gaster noises) (paps) ArE yOu oK gaster yEs
