The Great Agent Peggy Carter isn't immune to PTSD either.

Yes, he was the enemy and depending on who you asked, he deserved to die, but not to Peggy. No man, no boy who cried for his mother while he lay bleeding on this frozen forest floor should be left to bleed out and die alone. So sue Peggy for having a heart. Sue her for kneeling down by his side and shouldering her rifle, just to pull the boy against her chest. Sue her for wearing her heart just this once on her sleeve.
