in the future timeline that is the home of the x-man bishop (earth-1191), the x-men were wiped out in 1996 by someone recorded only as 'the x-traitor'. however, there was apparently one survivor of the attack, a man called "the witness." he had a cajun accent and long hair. he and bishop had an antagonistic relationship in that time. when bishop came to the past, he recognized gambit's face as that of the witness.
