I keep on saying Sil needs therapy lots and lots of therapy. The poor kid has been through too much at too young an age. Sil is broken and he is hurting and it is all so tragic. I feel sorry for the character because he has been so hurt. things are finally moving in the right direction to bring Vorten and Raten back. Sadly progress is not an end zone, and progress alone is not a victory. Sil needs a "W" more then any other character in this story. Besides we all are starting to think Sil is going to die in the end.
In the end, Sil needs a big hug the most. He has an emotional backpack filled to the brim and needing emptied. The time in shadow lock with Quinn gave Sil some temporary relief. Sil could channel his anger into practicing his combat abilities and by talking to someone he trusts like Quinn though Leo and Brock might even be better alternates and they seem pretty good at empathy.
There's another commenter on here that keeps saying that Sil needs to get some therapy - I'm starting to think that he's right. The thing about Sil is that I don't think that it's therapy that is going to have an end date. Sil was really f'd up on Blade Island and it may take a lifetime of therapy to sort him out even partially. He may never be truly healed but perhaps he can at least be functional.
