This is the general discussion post for the episode 3.13 "Terminal". Spoilers for the whole series are allowed here
Without explanation, Avon follows a series of secret messages to the artificial planet Terminal - an experiment abandoned 400 year ago to study the accelerated evolution of life on Earth. While en route, the Liberator passes through a strange cloud of fluidic particles that, unbeknown to the crew, begin to eat through the hull. Arriving at Terminal, Avon, who refuses to divulge what is going on, teleports down alone. Tarrant and Cally quickly follow to see what he is up to. Avon soon comes upon an underground base where he is captured by guards, but he later escapes and finds Blake in a medical recovery room on life support. In orbit, Vila and Dayna deal with the Liberator as the ship begins to fall apart. On the planet, Avon eventually discovers Servalan is behind the messages in an elaborate ruse to get her hands on the Liberator. She agrees to hand over Blake for the Liberator, but doesn't know the ship is doomed. Likewise, Avon is unaware that the Blake he met was only an illusion. Once Servalan's treachery is revealed, it is too late and she finally obtains the Liberator. However, before she can leave orbit, the ship begins to break up. As Servalan tries to escape by using the teleport system, the Liberator explodes.
