Hmmm, perhaps Methos's Chapp'ai was simply a newer experimental model? one of a kind to allow 2 way travel. Hmmm what if SG1 invite Methos to earth for a visit, and they're trying to give him a tour? tell him about earth? and of course he would feign ignorance and ask strange questions and generally mess with their minds.OH and of course he doesn't have local currency since he isn't from earth(supposedly) and tricks Jack into shouting his beers for the night/week *evil grin* and proceeds to run up a huge bar tab. Methos as mystic holy man, *chuckle* he would have such fun.
