Which two Doctors met in " Time Crash " ?
During the Virgin New Adventures , the Seventh Doctor was occasionally at odds with his subconscious memory of his previous incarnation as his memory of his past self became increasingly associated with the Valeyard , his dark , future self , but he eventually accepted his dark side and ' reformed ' his memory of his former self , although it was never established how the two Doctors would interact if they had met in person .
