The two DLC episodes are very similar to the fourth arc of the "Trial of a Timelord" season in classic Doctor Who, which had the Doctor trying to reach his Enemy Without in a dream-like world controlled by his foe. Each of the characters in the DL Cs even fills a very similar role to one (or two, once :P) of the major characters from that arc, with Alan as the Doctor, Mister Scratch as the Valeyard, Thomas Zane as the Master, and Barry as Melanie/Glitz.
