Derek would come to listen to Stiles explain what was going on with him. Derek held an expression on his face, that he was sure Stiles had never seen before. Derek actually showed concern for the little human at this point. "Even if there's no cure. There's always something." He replied as he came to watch Stiles a bit closely now.
"Just rest for now." He replied as he came to watch Stiles. Arms crossed over his chest for the moment. "When the time is right, we'll take the next steps to getting you better." He made sure to let him know for the moment.
