Chuck vs the Bullet

What's worse than being shot? Being shot, and needing to hide it from an overprotective sister who also happens to be a doctor. Chuck gets shot by a Fulcrum agent, and to protect his cover, needs to hide that fact from Ellie... which is easier said than done. Especially since she's not about to let him get away with it... and neither is Fulcrum. hurt/comfort (Ellie finds out story)
