- It stumped me for a bit, how did the Master get inside the TARDIS when Lee had the key? He used the one the Doctor kept above the door in a cubbyhole above the 'P'! How he knew about it is another question... but the Doctor and the Master have known each other a very long while after all...
- Alternatively, the Master picked the lock to gain entry. He was doing so in "Survival", but was interrupted by the Doctor before he could succeed. With no such distraction this time, he was able to break the lock.
