Isnt there an incosisteny between the two Psylocke sightings ?
In Wolverine : DOFP she is portrayed as the Hellfire Clubs Red Queen. This storyline is set clearly before Uncanny X-Men #141-142. In Captain Britains dream sequence of Excalibur #94, which happens around the same time, she is among Excalibur. There is no problem to get these appearances in order; in Wolverine DOFP #3, Betsy gets fried by Jubilees fireworks and Emma Frost states at the end of the issue that she has contacted Brian Braddock who will take Betsy to England once her rehabilitation is complete.
