First off, I stand by what I said in the first part, were it not for the use of androids here the Kraals could have been replaced entirely by Sontarans or even Judoon. That said, I loved how at loggerheads the Doctor and Master were here: this is basically an hour of one upmanship. Leela was great too, she's really growing on me. Overall, a very solid finale to a pretty solid first season of audios.
