I'm not going to take sides but I believe both people should drop the topic and any lingering animosity towards each other.
Cuz both of you are gonna be in this RP so you might as well cuddle and have sex or sumtins idkwadevsandbehappy. Or kill each other in the RP, thats fair.
I don't intend for my character to change missions often. I mean diaries are based off your characters and a person obsessed enough to make a 'mission diary' would be that guy who wants to unlock all achievements in a game, even if it meant spending hours and hours of time.
