This is a complex issue. On the one hand, in the stories where past Doctors have appeared solely as echoes in the story's current Doctor's mind, it might be said that shouldn't qualify as a multi-Doctor story because those past Doctors are not really present during events. On the other hand that would disqualify Zagreus, as the past Doctors in that story are initially Zagreus' warped recreations of the past Doctors taken from the Doctor's biodata, and later their aspects in Eight's mind; could we justify not counting Zagreus as a multi-Doctor story?
