Episode: "Here's to Future Days"
The Friday Night Lights alum plays a soldier with a mysterious pain in his leg. He asks the doctors to amputate and fit him with a prosthetic so he can return to duty. After much protest, the docs go through with it. Charlie becomes the inspiration for George to join the army, which leads to him heroically jumping in front of a bus to save a woman before he was scheduled to ship out.
