Jonah switches into new body and catches attention of some young Lukas. They start and affair because it sounds like quite isolating thing to do - steal away spouse of someone you’re related to. And who’s Jonah to say no to fresh new Lukas?
You know in reality where Peter doesn’t die and Elias’ ritual fails once again for some reason.
Anyway Peter hates it even though he should enjoy the Loneliness of being cheated on because he (unlike Jonah) actually has some feelings for him.
And so it goes on and it’s soon very clear who Jonah prefers now until one day he tells Peter that they should cut contact - he’s getting too old for him and also Jonah is basically doing Peter a favor because it’s not good for avatar of the Lonely to get so attached…
