Saving Sayward's slaughter
Okay We take Resurrection of the Daleks out, of the run. We can replace it with another story but the upshot is that Tegan leaves at the end of that story. (By the way, Tegan just walks out of of the Tardis, with only the clothes on her back-in London in 1984-She has nothing. No where to go.. OR We have the Master kill, Tegan in planet of fire. Now yes this happened recently with Adric So this might be a problem OR We do not introduce Peri in planet of fire. I have nothing against Nicola Byrant but for our purposes I think it works better later if we have Tegan Jovanka. So in Caves of Androzani Peter Davison saves Tegan, rather than Peri. So we have the twin dilemma but this time, we have Tegan. Tegan handles the regeneration better, and we do not have the Alien spies too. Maybe she tries to get Doctor into the Zero room. Hell you are not going out like that Doctor. So instead of a train wreck of a story, we have a cancelled train, due to flooding.. But...
