First of all, I love this song, you did an amazing job Puffballs, second of all, I don't know if Seawing animus is here but there is one where you betray Ellie. I don't know the spooked ending but there is one where you have to let the timer run out at the crashed truck ending and then you get presumed dead.
So either try betraying Ellie and not helping her up or try to charge at the guard and follow the story there. Feel Free to read this if anybody else didn't understand. Kinda wish we could reply to other people's reviews but whatever
