Slight modification of BGA's original set up. Watcher instead of BG does not allow the tracker to find the BG night 1 to prove himself and render the traitor/CC useless.

If tracker claims D1, maf let it go (even with a guilty, most likely) and then shoot the tracker. Traitor puts a guilty on a random D2. Traitor can claim with a fake guilty D1 as watcher if he wants to force the watcher to out, or hang back to CC if the watcher really does have a guilty (Alcoway).
