Dipper: "....What in the holy hell--" (Dipper glanced around nervously.)
Stanford: "... Fascinating! We've been transported to a different dimension-- possibly different time-line!" (Stanford said, not finding the situation weird whatsoever and writing in his journal.)
Stanley: "...Great." (Stanley looked unimpressed, and had a gruff expression on his face.)
Mabel: "WOah... Cool! :D" (Mabel looked completely unphased by the whole situation.)
Michael: "...." (Michael didn't notice the new people whatsoever, since he was just laying on the couch lazily, his eyes barely open.)
Elizabeth: "...Wow. I think we've all finally went crazy and are hallucinating now." (Elizabeth said sarcastically, while sitting next to Michael on the couch.)
William: "One normal day. Just ONE." (William sighed, taking a sip of his coffee.)
Evan: "..!?" (Evan was too stunned too speak, and also scared. Normal reaction from him.)
