It had taken less than a full minute before Elisabeth decided to rescue the boy. It had taken less than a full minute for her heart to reach out, to ache with something unfamilar in some bloody maternal love for Arthur. Some nutbar instinct to protect and save him. Alright, so it wasn't nutbar, but...he wasn't even her child, her sibling. And yet it was wrong to just let him be treated...tortured the way Ryan was. She could offically admit to loving the one-time stranger. She would bring him home. Her home. If it meant stealing him from Lex, so be it, she was ready to adopt (oh, Christ, what was she thinking???), she was ready to rightfully care for this child when Luthor had failed.
Without seeking help, without hesitating any longer than was needed to prepare, the mutant tapped into the children's minds and found the location of Arthur's horror. She staked the place out, waiting impaitently in silent torture until the nightmare with blonde hair left. [Arthur, love? I'm here. As soon as that bastard leaves, I am taking you away from here. I promise you, you will be going home with me tonight.]
