Powerplay picks up from where Aftermath left off, including a recap of the last few seconds.
"What are you doing on my ship?"
Tarrant is not alone, he is accompanied by Deputy Prime Minister Klegg (TEH SATIRES!111) who is played by Michael Sheard, an actor who was in Doctor Who so many times as different characters that there is bound to soon be a story arc where the Doctor goes looking for the reason why so many mannys he met looked like Michael Sheard.

Avon, who still doesn't know that Tarrant is really on his side at this point, thinks he is going to have to fight for control of the Liberator, and to ensure that he is still the most handsome character in the series. For the first time Avon has some serious competition in that department.

Tarrant and Dayna join the Liberator's crew and are now main characters. Now the best season of Blakes 7 has really begun!
