Their dynamic rly reminded me of Saraberry Heather animatic where Heather was done with all pressure and finally did homicide with JD.
*Spoiler*
I assume this was happened after Killerchat? like he came back to the Angelwood after the discord was created and already aged to 20 something now. The way the game immediately get back to the beginning at the moment we reached to the end again, like a loop, made me think that everything actually never happened. It was all Ronin's imagination that Ther finally accept themselves and fucked the town up with him. He just imagined all of that the moment he saw Ther's face at the Angelwood.
