Zombie Exodus and Zombie Exodus: Safe Haven Hints and Tips

Does anyone know how to unlock the Aj Austin premade character for part 2 I have the 75 skill attributes but it’s still grayed out

I’m guessing to stop people from being stand offish. Like other survivors or when people in camp get into arguements

Also your reputation/plan of action when dealing with other groups, more than intra-group relations. Do you shoot or ask questions first?
