Clearly they were friends before the Master went insane. I’ve watched the series for decades and usually love every second. Their previous friendship is also part of cannon. What has also been long established as cannon is that there are only 12 regenerations available. One of the flaws in the series is that the Master is currently at more than 15 regenerations, and the Doctor is currently on regeneration 14. Many Whovians, myself included, have long desired an explanation for this. This episode is an attempt to provide that, and it fails abysmally. The viewer is left with more questions than answers; hence my confusion.

Not to mention that when the last Doctor was on that time dilated ship (10x11), The Master killed Missy, his future self, during her regeneration cycle, which was supposed to have killed The Master for good. I was like WTF when he first showed up this season.
