Episode menu

The Tertiary Phase, Episode 4 - Fit The Sixteenth

In which Arthur Dent attempts to escape from a lifeform whom he keeps accidently killing, learns how to fly, and gets hit in the small-of-the-back by an airborne party.

Further details

The creature who diverted Arthur to the damp dark room he is in now calls himself Agrajag. He claims that he has been killed by Arthur in all of his reincarnations. Amongst these include being a cow that Arthur had a stake from, a fish that Arthur caught and did not like the taste of, an oyster, the man who had a heart attack at Lord's, the rabbit he turned into a bag and the bowl of petunias from 'Fit the Third'.

Agrajag also claims that Arthur killed him at Stavromula Beta. However, Arthur claims that he has never been there. Agrajag discovers he has caught Arthur too soon. He still tries to kill Arthur, but Arthur escapes by flying (the trick is not think about it). As he flies, Arthur gets hit in the small of the back by the party he was meant to travel to.

Arthur gets himself, Ford and Slartibartfast into the party. While Ford and Slartibartfast look for the Silver Bail, Arthur is distracted by Trillian, who is being treated to drinks by Thor, the Norse God of Thunder.

While searching the party, it is discovered that the Silver Bail is the 'Rory Award for the Most Gratuitous Use Of The Word Fuck In A Serious Screenplay'. However, before they can get it, the Krikkit robots attack the party and take the Bail.

Arthur is still annoyed about Thor chatting up Trillian, so he tricks Thor by asking him to step outside, resulting in Thor falling out of the flying party. Slartibartfast gets everyone together so that he can go to the Wikkit Gate in a final attempt to stop the Slo-Time Envelope being opened.
