He didn't understand where the Cajun was coming from - though, the Doctor sympathized. There was a time when all he'd wanted to do was travel alone for the rest of time.

"I could not leave these people behind, friend or not. I have a duty, a responsibility, a code. I wouldn't leave them. I wouldn't leave you."
