Hari and
Rowan:
Rowan could be a friend to Hari, he's 12 distant and needs more caring people. And honestly Rowan reacting to being baked cookies and hugged would be amusing since Rowan is sorta stubborn and would be so unamused as well as awkwardly adorable.
Duke and Rowan:
While Rowan is not really powerful or anything, he is quite stubborn and has his own morals. Perhaps we could do something with these two? I'm sure some conflict or something could rise from these two with Rowan's past.
