Last night, I've watched the Season 7's episode Hero, which I'm sure 98% of users on this wiki are familiar with that episode. A few episodes before this, Chloe used her power on Jimmy and healed his wounded index finger from when she stepped on his hand in the elevator scene from Gemini. But on Hero, at the Daily Planet scene when Chloe told Pete "Don't let another light year pass before I see you again," his arm was in a cast from when Lex tortured him for kara's bracelet. Pete even told Chloe that Lex told him she had a meteor power. This would've been an opportunity for Chloe to heal Pete's arm, giving to the fact that this is not a life-threatening injury, meaning that she'd be fine. Why didn't Chloe help her friend?
