Blake and Jenna teleport down to the planet Horizon first and get captured. The rest of the crew then have to decide who has to teleport down and get captured next.
"I am not expendable, I'm not stupid, and I'm not going."
So it is Gan and Vila that teleport down and get captured next, then Cally teleports down by herself and gets captured.
"And then there was one."
Avon is left alone on the Liberator with only Zen and Orac, and he has the dilemma of whether to teleport down to try and rescue them and maybe get captured too, or to fly the Liberator away to safety.
Paul Darrow acts these scenes magnificently (as always), and you can see the agony of decision in Avon's face.
It looks as though he is going to decide to fly away, as painful as that is for him to leave Blake and the others behind...
... but in the end the decision is made for him when Zen tells him that Federation Pursuit Ships are on their way, which means he will have to try and rescue the others. Avon smiles because he is happy really that he will have to do this.
Avon teleports down and rescues the others in an exciting scene on film with plenty of explosions and Federation baddys getting shot.
Meanwhile Blake, in an attempt to not be upstaged by Avon's action sequence, takes his top off. This is very rude - you can see his moobs and everything!
Avon is clearly impressed by the sight of Blake shirtless. Insert Galaxy Quest quote here if you want.
With the score at one all, Avon sadly refrains from trumping Blake by taking his own top off.
Blake puts a shirt back on for the last scenes aboard the Liberator, much to the disapproval of Avon and the viewers at home.
Horizon is a good episode, but it is caught awkwardly between much better episodes that come before and after it.
