Theory:Doctor Who comic strip discontinuity and plot holes/4-Dimensional Vistas


 * The Time Meddler's TARDIS is stuck in the form of a police box. However, in The Daleks' master Plan, the Time Meddler was able to correct his TARDIS' chameleon circuit, and it was last seen materialising on an ice planet in the form of a block of ice.
 * He could have deliberately changed it back to that form. Might appeal to his sense of symmetry or something, seeing as he laid so complex a trap for the Doctor.
 * Except he didn't set the trap for the Doctor. That was just a side effect of the experiments in time. Note that the Time Meddler shows clear surprise at the Doctor's identity right before he is blasted into another dimension. I would instead suggest that the Time Meddler's chameleon circuit is on the fritz and it stuck in the police box form in much the same way the Doctor's TARDIS did.
 * It's poor continuity. In The Daleks' Master Plan, the Doctor messes with the Time Meddler's chameleon circuit, leaving his TARDIS looking like a police box. However, the Time Meddler repairs his chameleon cicruit(something the Doctor was never able to do), and when we next see his TARDIS it blends into the surroundings on the ice planet. Whoever came up with 4-Dimensional Vistas was likely ignorant, and didn't know(or perhaps simply ignored) that the Time Meddler's chameleon circuit had been repaired.
