Here’s where I got to in the “Nerd Boys and Wendibros” Until Dawn WiP.
This is mostly me being As You Know, Bob self-indulgent with my fanon lore. The idea here is that eating a wendigo’s heart (which, remember, we saw Josh do earlier on in the series) is what causes the “hybrid” style wendigo. This entire story was basically an excuse for Josh to have a Big Damn Hero moment involving a fake-out where he pretends to eat Ash. Basically because lololol fake love triangle fuck that basically.
