This is basically just a book of head cannons of TFF

Steve and Bryan successfully separate themselves using the Portal Timer, but end up throwing themselves back in time too. Now back at the first pizzeria, Bryan has to act like he isn't a half rotted corpse, Steve tries to hide his identity, and Molten has a suspicion that something is wrong. (We also get other universe Bryan's including Scp, Olympus, Hero Origins, and maybe more!)
