This might have been brought up before but… Dipper Pines becomes a historical figure, seperate from Alcor entirely. The earliest known text on The Boy Who Saved The World, “The Bravery of Children” as it was later called, was a compliation of documents gathered only a few decades post-Transcendence by a Gravity Falls librarian whose name is lost to time (aka Henry researching how Mabel’s incorporeal brother became a thing because he was too shy to ask). It’s mostly diaries and Dipper’s Guides.

Ya know how parents get in the bleachers at kids sports games? Imagine Alcor going to a soccer/baseball/weird-post-transcendence-sport game and just “GO, YOU CAN DO IT, BURN THḚ͈̙̬͇̼͂ͣͦ͆͒̀͠I͓͈̭͕͝R̟̤̱̩̝̔͝ ̠̳ͫͩ͒ͅS̪̥̖̟ͤ̒̂̔̋ͅŐ̤̘͇ͦ̿͌Ú͙̣͔͈̯̲̮̔͂ͥ̽̾L̖̃ͭͧ̉ͨ̒͝S̷̰̥̫̬̎̀̉̐” and him trying to play it off once everyone starts staring at him.

I’m going to immediately attribute this to both Mabel’s triplets, and Maddie.
