Lex chuckled as he caught Liz and kept her from falling. He asked Little Blue to land while he used a small rejuvenating technique to help alleviate the stress on Liz's mind and help her cope, allowing her to wake up.
The truth of the matter was that Liz hadn't slept in days in preparation to save Harriet from that ship, faced near capture from an Immortal and was finally rescued from her brother, who she hadn't talked to in years. It was a bit much.
"Do you want to get some rest first?" Lex asked as they stepped off the whale. He could tell just how mentally and physically drained she was, though she didn't show it.
"No, I'm fine," Liz said as she summoned an inhaler and took a puff. The next moment she seemed completely recovered, as if she was ready to fight a battle.
