Kay shook her head at Bane's apology, none of this in her eyes was his fault. "This isn't your fault Bane. We both should have checked, not just you but our priority was getting them to a safe place" she replied to him, as she saw both John and Serena trying to stay conscious. 

She walked over to John and knealed down in front of him, placing her hand on where the attachment was and began trying to heal him again, which she managed to do. She then went to Serena and did the same thing, but after healing Serena's burns she slumped onto the floor on her arse sighing as she felt burned out but okay. "THey should be okay now" she told them, Sam rushing to her sister's side and kneeling down to check on her.
