He shrugs, honestly not sure if it was possible for him to worry less. He felt worried all the time, even before coming here. At least at home he didn't have to worry about randomly finding himself under the sea. Home if something bad happened he could leave, he could do what he thought was best. Here that was impossible.

The truth was that with everything being as chaotic as it was here he was afraid of loosing Susan without ever getting the chance to stop it. He'd always been afraid of loosing his brother, but never had the threat of danger felt so strong. He doesn't want to scare Susan, he's dumped so much on his brother already, said things he should have kept to himself. As usual when it came to the things he felt the most strongly about his words failed him.

"I don't want to loose you..." Susan was all he had. The last of his kin, his last chance. But how could he hope to protect Susan from the threats of a world he didn't understand?
