The one where the quest for the Key to Time finally comes to a climax...
Drax reduces first the Doctor, then himself, to miniature proportions in some bizarrely misguided attempt to escape the Shadow's Mute, but actually makes the whole situation much worse because before he was miniaturised, the Doctor left the TARDIS door open. This means that they are now powerless to stop the Shadow waltzing into the TARDIS and snatching the five segments of the Key to Time for his boss, the Black Guardian. Well done, Drax.
Except the Mute is not the sharpest knife in the box and gets distracted by looking for the Doctor rather than taking some initiative and grabbing the Key. This is perfectly in keeping with the rest of the plot at this point, which has ground to a halt somewhat. The Doctor can't do anything because he's roughly the size of an inch; Romana can't do anything because she is the Shadow's prisoner; and the Marshal can't do anything because he's still stuck in a time loop. The only character who can do anything to move the plot on is the Shadow, who is now free to obtain the Key to Time and ultimately destroy the Universe.
