Talk:W. D. Gaster/@comment-27937587-20160308104210

I have a thory: I think that Grandpa Semi is a reference to the time paradox GRANDfather PAradox, where a time traveller kill his own grandfather before he had the father of the time traveller. So gaster killed his own father because of curiosity, just like Flowey, to see what happens, and the experience finished by both of them being erased from the world/timeline. (Spooky)
