Do you think the ending will result in some sort of weird loop where it turns out Dirk IS Bro, Jake in Grandpa harley, etc and thats why they knew stuff was gonna happen? The convo in the update with dave and Dirk felt very forshadowy for stuff like that.
No, after hearing how shit Bro was to Dave, Dirk would never put him through that. Besides, we already know that’s not true since we saw Grandpa land on his meteor.
