If that isn't bad blood between former friends, then I don't know what counts. What do you think? These two have had it in for each other since Spike left the Syndicate. Remember what Spike told Vicious in "Ballad of Fallen Angels"? "I'm only watching a dream that I've never awakened from." How about "The Real Folk Blues (Part II)"? "We're the only ones that can kill each other."
