What is this "hug" you speak of, Gaster knows nothing of hugs. Meaningless distractions!! And potentially dangerous, god forbid he get attached to these things.

This would fall after this comic roughly, with the two of them out of the tubes for the first time. Sans is unconscious at the moment, thus why he's not reacting to all the screaming. He had a harder time adjusting to life outside the Mystery Goo (tm).

Papyrus is getting a lot of facetime in these lately but I just could not picture Sans offering Gaster a hug, even if they were just "born" like so. SO PAPYRUS STEPS UP AGAIN
You'll notice they do not have their handplates yet. Could that be one way to prevent attachment? HMM
WHERE COULD THIS ALL BE GOING


Done entirely digitally, the thumbs were in pencil though.
