Wyll is a very flawed being, as are Gale, Lae'Zel and Astarion. Trauma doesn't always look the same. But, I can't confidently say how his looks like. It's very possible we haven't seen Wyll struggle yet.
What we do know about his trauma is the anger. Anger can lead him down a dangerous path or to redemption. Intense and uncontrollable anger is as much a shade of trauma as fear or panic attacks. Anger is more common a response after acts of violation of one's body. It does not feel like normal anger. It's so intense, it's beyond description. It's easy enough to hold back when it's uncalled for, but when you are right to be angry and get /this/ angry, it's considerably dangerous to other people.
I don't know If that's what Wyll's mind looks like. but, I'm quite interested in what they're going to do with him. I feel like he has much more room to be bend one direction or other than Gale or Lae'Zel.
