Talk:W. D. Gaster/@comment-29386858-20160702175610

I theorize that Sans and Papyrus are remnants of W.D. Gaster. Apart from the hinted associations with Gaster and Sans's affinity for science, there are two instances of a character thought to be Gaster speaking: One in the infamous Entry Number 17, and one in that room where Premonition (note that the only time it plays in usual gameplay is in a situation involving Sans) plays. In Entry Number 17, he speaks in all caps with no asterisk. You know who else speaks like this? Papyrus. In water_redacted, the mysterious figure that could be W.D. Gaster speaks in all lowercase with an asterisk. You know who else speaks like this? Sans.
