Well I originally just wanted to get rid of CHARACTER_Player2 but I liked the RP system and there are quite a few dialog event that need player2 around so I turned player2 into a cat with some cool behavior. I just like messing around with game code more than playing to be honest, I did this with Stellaris as well
I'm not sure if a summon will still qualify as player2, I haven't messed with dialog yet. I check it out but I think I should just band aid it with a timer since there isn't a way to track another player through a charScript (or it's not even considered because it's too far away I should say) and Osiris lacks the commands. I did the same thing with the character template in character creation because when the gender is changed, it overrides the scripts and Osiris can't measure character templates for a trigger so I just start/stop a timer. I don't like the Story code at all, it seems far too limited.
