Literally, just keep walking the path we were already on. Befriending Penny, Harrison and Damien. Three Protagonist tier friends of Sol who do not have the Fate Demerit and can therefore help us ward off the grubby hands of fate.
Hell, Penelope has literally just proved that her angel bullshit can allow her to flip off the Architecture and Fate trying to screw us. And Damien as the Hangman who is more Odin than Odin, can likely also do bullshit with Fate later on.
We already have the necessary allies to not be fucked by Fate. Sol's situation is not helped by deliberately introducing a massive weapoint in his fate and soul, and thereby all but inviting the Architecture/Karma/Fate to fuck him.
