spoilers for The Punisher
[...] Lewis Wilson. He was a veteran who had extremely severe PTSD and...well to be honest, he was having a tough time adjusting to civilian life. He started to become more extremist right when I was in the middle of engaging with Senator Ori regarding gun control, and he sent me a letter to publish in the Bulletin because he thought I was sympathetic to his beliefs and wanted me to choose a side, then set off several bombs around the city. He even called while I was on a radio show with the Senator. A few days later I was interviewing Ori in a hotel, one-on-one, and he essentially stormed it and attacked the private security the Senator had hired, and managed to take me hostage. Frank showed up to save me and followed us down to the kitchen. We both tried to talk him down, but he had a bomb wired to himself. While he held me, Frank sent me hints on disarming the bomb and I managed to do it and shot him in the foot to get away while shoving him into the freezer. He rewired the bomb and set it off himself. He killed himself.
