Theory:Doctor Who audio discontinuity and plot holes/Terror Firma


 * Davros is obsessed with the fact that the Doctor "destroyed Skaro". However, Davros already knows that Skaro wasn't destroyed (War of the Daleks), and it is established in the New Series that Skaro wasn't actually destroyed.
 * It is very possible that War of the Daleks did not take place in this continuity, or if it did, that Davros has not experienced it yet. Simply because Skaro exists again after the Time War does not mean it had not been previously destroyed. Perhaps it was early on in the War that Skaro was resurrected, only to be devastated along with the rest of the universe.
 * Adding to that, War of the Daleks also established that "Skaro" was the Kaled word for "home". So even if Davros is aware of the Skaro that was destroyed being Antalin, he might just be obsessed with the fact that the Doctor destroyed the place he thought of as home. Oddly sentimental of him, but it sort of works.
