Joking a side I can understand some people thinking this. I mean if Mabel hadn’t given Billendin the Rift, then Weirdmageddon wouldn’t have happen. But if Ford had allowed Dipper to tell Mabel about the Rift then, That wouldn’t have happen. BUT MAYBE Ford
I'll tell you guys what happened. Blendin Blandin left a message for them in journal there is a nightmare realm in the portal along with other dimensions, there is a stupid tattoo under Fords sweater, and Dipper's real name is.
