Dirty Den

Den before dirtyness was once a slick-haired assistant to Commander Lytton on Doctor Who named Kiston. He was based on a satellite called Riften 5 which orbited the planet Vita, 15 centuries in the future. Den's Doctor Who link wasn't forgotten when years later Lytton made a surprise time-traveling trip to Walford. He popped into the Queen Vic and mistook Den for his former assistant. I guess this isn't surprising because they are sort of the same person pretending to be someone else for the sake of a TV programme. 

  But this small incident only recorded in the Doctor Who magazine goes a long way to explaining Den's miraculous reappearance on Albert Square. I proffer that Den's murder in 1989 that turned out to be only an attempted murder in a terrible twist of appalling story-telling was actually a real murder and that the subsequent return of Den fourteen months later was actually a pre-1989 Den time-traveling forward to 2003. However, this explanation doesn't explain the second murder problem which would have made it difficult for Den to return to a time before 1989 to allow himself to be genuinely murdered. This can only be explained when we consider the assumed shape-shifting potential of Lytton who I reckon must of taken on the shape of the dirty one and allowed himself to sacrificially murdered in Den's place by the three angry ladies that Den had pained. This allowed Den to return to the 80s to pay the Sixth Doctor Colin Baxter the tenner he owed him and allow himself to finally meet his end and satisfy the watchdog of coherent narrative structure. Why didn't Eastenders just explain this to the audience at the time and avoid accusations of reintroducing Den just to steal viewers back off of Corrie?
