The one where the Doctor works out why Kroll is so big...
After a tedious reprise going as far back as Rohm-Dutt's death, the episode continues with an anti-climax, as Kroll decides to simply go back to bed (sea bed?) and not terrorise the Doctor and Romana at all. But Kroll does re-emerge elsewhere to terrorise the terrified Swampies, and this time the terrible split-screen effect just gets worse. I thought it had been bad enough so far, but when Kroll attacks the Swampie settlement, the harsh line dividing the screen between the Kroll puppet and the actors on location is embarrassing. It's the best they could do, blah, blah, blah. Yes I know, but their best on this occasion just wasn't good enough!
Meanwhile, at the refinery the technicians are turning on themselves, or rather Fenner and Dugeen are turning on their increasingly megalomaniacal leader. Thawn's thirst for genocide hasn't exactly come out of nowhere - he's made no secret of the fact he thinks little of the Swampies - but his rather steep descent into madness has been signposted less subtly. The truth is that Neil McCarthy isn't equipped to portray a nuanced collapse of this man's sanity, so all we get is a very melodramatic face-off between a man with a gun and a man with a conscience.
