Kara was almost killed at the Stride gum factory when a piece of scaffolding came loose and almost fell directly on her while she was stripped of her powers. She was saved at the last minute by Pete Ross, who was temporarily metahuman due to kryptonite-infused chewing gum.
Kara was seriously wounded after being attacked by Faora, but Chloe Sullivan uses her Brainiac-like powers to open a portal to the Phantom Zone. Clark is pulled into the portal, and brings Kara back with him. Back on Earth, Kara is instantly healed as her powers return.
