I was reading through his character page and was extremely taken with his character Hyde who suffered abuse from his brothers as a child. And it made me think of Ruko and their childhood situation.
I was hit with a -rather vivid- image of the two passing on the street and making eye contact. Each one sort of just...knows the other is damaged somehow. And while I feel Hyde is too hardened to care and Ruko would probably be off on official 'Family Matters', I could still see them holding that eye contact like they now share some dark unspoken secret between the two of them.
