>>106574599Before Flashpoint, Lena Luthor was a paraplegic. She was a total invalid being taken care of by her daughter in Smallville. Lex escaped from jail, and Connor tracked him down. Turns out that Lex wanted to be caught.
He cured Lena’s paralysis in front of Superboy, to prove that he could do whatever he wanted, and just as she got out of her wheelchair, he injected her with something else, which puts her back in the state she was in before.
