He knows he could find a different doctor, but he doesn't trust any of them like he trusted Henry and, more than anything, he doesn't want to start over with someone new.

He also doesn't want to push his problems with his brother's death and Mexico onto anyone he loves.

"I know," he says after a moment, smiling faintly again. "Sometimes it is just... zu viel... too much."
