Duncan MacLeod: "What're you doing here?"
Joe Dawson: "Keeping tabs on you."
Duncan MacLeod: "Yeah? Well somebody should've kept tabs on that psychotic asshole back there."
Methos: "Didn't you get it back in London? These guys don't play by the rules."

"You know a little about Buddhist monks. Some of them come to cherish life so much that to step on an insect or harm a blade of grass becomes a violation of their creed, so they place themsleves under an extreme form of protective custody, a sanctuary of sorts. Well, for an immortal who comes to abhor the bloodshed, there's a similar solution, a way to be removed from the game forever. Though the price is unimaginably high, but you are, for all practical purposes, protected from the violence within you."

Methos: "I liberated that from their lost and found."
Duncan MacLeod: "There's blood on it."
Methos: "I didn't say it was easy."
