Forum:Hiveswap theory

so you know that trailer https://www.youtube.com/watch?v=ptSacF8xb8k well the curtian in the part about the big secret looks awfully familiar to the curtain in undertale. as you remember nobody has found out what this curtain is, so it would make sencie that hiveswap would fill the gap in undertales plot. imean just look at the two curtains and tell me they are not the same. (if i am wrong sorry)
