McKay realises that Paudge could be the rat in the station they have been looking for (as we all know he is). This comes as quite a shock to Sergeant Tyrell, but McKay assures her that he has a reliable source giving him reason to suspect that Paudge has been the one leaking information to Beady ‘Lazer’ Burke. McKay is soon questioning Paudge about how he is getting so much info on Beady's movements, with Paudge telling him that it is in fact petty criminal Ollie Coyne that is informing in, but will Ollie back his story? And more importantly, will it be enough to convince McKay? Elsewhere, poor Michael is left heartbroken when Siobhan discovers she will be moving to Thailand sooner than expected. Patricia will be no doubt be delighted anyways!
