The Tenth Doctor and the Fifth Doctor meet in a special taking place in between 'Last of the Time Lords' at the end of Series 3 and 'Voyage of the Damned' at the beginning of Series 4. You have been warned: it would most likely be quicker just to watch the episode, seeing as it's only 7 minutes long, than to read the following recap. As well as YouTube, it can also be found on the season 4 DVD. Credits roll. David Tennant AND Peter Davison's names in big words. (Literally the only thing that could have made this special better would have been to use the Davison-era version of the title theme.)
