Synopsis: The Doctor's new companion is something of a conundrum. She waits on him in an all-too-servile manner, and the Doctor can't quite figure out why. He at first believes it's because her former master, Skaroux, has mistreated her badly, stripping her of any independence.
But when Skaroux captures the TARDIS in a tractor beam and boards the ship, a different picture of Olla emrges. She's essentially "faking" her role as a servant in order to make a clean getaway--with most of Skaroux' fortune. Not wanting a criminal on board, the Doctor turns her over to Skaroux for eventual trial. The Doctor then travels on alone.
