Very cool episode

The Antarctic section of the story is pretty intense, some seed pods are found of alien origin and infects a crewmember while thugs from an eco-terrorist back in England are trying to steal it (and another pod)

The England section of the story is probably less interesting but still pretty good, the villain is actually fairly unique for up to this point. Usually the pro-environmental character is a protagonist of the story, but this one takes it to such an extreme that it is anti-humanitarian (and anti-animal as well tbh). Also he has an organ and plays the most hideous music I have heard in my life.

The Krynoid is pretty scary as a villain as well, it kinda reminds me of a less overpowered Gravemind, especially since it seems to have an intelligence.
