Adam is still down in Australia, interviewing Michael Sevior and discussing his Destroy list.

Adam interviews Scott Sadler, a long-time Gerry Anderson fan who introduced his children to the Supermarionation shows, enticing a whole new generation of fans.

Adam and Scott continue with their discussion as they go through the episodes that Scott wants to destroy.

Adam interviews Maria Alice Gray, a cosplayer known for portraying Marina and Lady Penelope. They also discuss the 2004 Thunderbirds movie (despite Adam not being a fan) and of course, the episodes that Maria wishes to keep.

Adam and Maria cover her Destroy list as well as discuss S.T.O.R.M., a book series written by Maria that is inspired by the works of Gerry Anderson.

Adam covers the Keep list of Dave Munday, author of Writing in the Sand, a sci-fi novel that was (naturally) inspired by the works of Gerry Anderson.

In addition to Dave's Destroy list, the football fanatic selects a line up for his Anderson-themed football team.

Something unusual has happened on Keep and Destroy. There isn't a brand new guest this time, but previous guests have come back for more, but who are they? Fortunately, Dick Spanner finally debuts on Keep and Destroy, maybe he can help.

AJ, Danny, Emma, Maria and Michael return once more to throw one last bit of shade at those they wish to Destroy.

Keep or Destroy? Well, the time has come to make a decision and Adam has chosen to "Destroy". Keep and Destroy comes to an end as Adam picks another five to Keep and five to Destroy.

Although the finale came and went in the last episode, you can't have a Gerry Anderson show without a flashback episode at the end ...
