Personality: Up to you but the one he has in Grace and Frankie could be fun!
Role: @emma ' guardian. Get ready for fluffy but also sad plots. He really adores her and wants to adopt her but he's older (obviously) so he would have a great deal of trouble there. He's also one of the good guys and she'll show occasional signs of 'darkness' which I imagine if she eventually goes that way he'll be heartbroken.
