Another brilliant premise to finish off this set. The Valeyard switches lives with The Doctor, even convincing Mel. The Doctor and a new companion fight for his life. Before he realises he must instead end it. Colin Baker finally gets the hero's death he deserved. A spine tingling performance. The Valeyard's reveal at the end and the terrible decision The Doctor is forced to make is great drama.

Just finished @josh_snares brink of death animation and OMG this animation does not only the episode but Colin’s final moments justice highly recommend
