You are doing a good job of showing the stress, fear, and grief that Clark is going through. He had major trauma in the Games. No wonder it will take him awhile to work through it. I hope he can bring himself to talk about it with Martha.
Yes, Clark is going through a rough time. He's dealing with PTSD and depression, and he doesn't want to talk about it. He wants it to go away, but that's not happening.
