UK cable channel Disney XD airs the 11th episode of K-9. The Australian-made series features no Doctor Who-related characters other than K-9. 
Professor Gryffen’s dimensional gateway activates by itself, something which should be impossible; before forcing it to shut down with brute-force firepower, K-9 is able to determine that an outside power source is the cause. Strange jumps in time begin occurring, but only Starkey notices them. An inflamed area on Starkey’s arm also begins to itch, and a blood test reveals alien matter causing Starkey’s immune system to go into overdrive. Gryffen recognizes the alien material, remembering an incident in which a couple of scientists implanted themselves – and their young son – with alien DNA. The dimensional gateway reactivates, and Starkey remembers how to close it again, but this isn’t a new incident: it’s the same incident repeating itself… but only K-9 believes him.
