Howling:Cross Dimensional niggle (Curse of Black Spot)

The spaceship that occupies the same space as Capn Avery's ship is said by the Doctor to exist in an alternate dimension (with portals between the two worlds via reflections). The adventure ends with Avery taking charge of the alien ship to sustain his crew who are reliant on the medic programme for life. I assume this means Captain Avery is now living in the alternate universe with son and crew. If so, when the TARDIS dematerialised from aboard the pirate ship to be found on the alien craft, where the Doctor finds it, has it returned to the original dimension? Because in A Good Man Goes To War, Captain Avery is one of those who assist in Amy and Melody/River's rescue (time's passed, the Captain seems to have got his son free of the medic programme): is this because a) Avery's spaceship is interdimensional, b) the Doctor has transported Avery's ship or c) the action all takes place in the alternate dimension?

I'm guessing the answers simply 'a'.

Its either A or B. A Good Man Goes to War features characters who we know are from the original dimension such as River and the spitfire pilots, and characters who the Doctor has met before and are probably from our dimension such as the Sontaran and Silurian. The ship can either travel between dimensions, or the Doctor brought them back to our dimension either at the end of Curse of the Black Spot or just to join his army.Icecreamdif 20:21, August 13, 2011 (UTC)

I've read that Curse of the Black Spot was originally to be shown later, after the season break. Does this mean that Captain Avery would've appeared at Demon's Run without us knowing who he was? Or did they add Avery to the Good Man Goes to War script? It might just have seemed a good recent ally to add to the mix. --Makgrey 20:46, August 13, 2011 (UTC)

In favour of option "a": Something created the portals between dimensions. It could well have been the alien ship that did so. Also, adding Avery to A Good Man Goes to War (and therefore shifting The Curse of the Black Spot) might have been done because Jack Harkness was originally intended to be in A Good Man Goes to War but John Barrowman's schedule didn't permit it, so he had to be replaced. By the way, Captain Henry Avery has been mentioned before in the show, though he didn't then appear in person: His treasure provided an important plot point in the First Doctor story The Smugglers (1966). --89.242.67.144 21:09, August 13, 2011 (UTC)

I would think that if Jack had appeared in A Good Man Goes to War, he would have been given a larger role than Captain Avery was. Most likely, Avery and Toby were added to the script after the schedule change. After all, they didn't really have a major role.Icecreamdif 21:32, August 13, 2011 (UTC)
