That said, evil!TARDIS in Zagreus made me uncomfortable. I think of the TARDIS' sentience as ineffable. I find it silly to ascribe it emotions like jealousy or annoyance.

Interesting! That's actually one of my favorite bits of the audio because while I don't think the TARDIS has human emotions normally, seeing her made to have them by Rassilon and whatever other forces were at work broke my heart. But yeah, the whole thing is just magnificent. I can't think of a single actor who didn't bring their A-game on that one.
