Katy has reached breaking point and has decided to hold Oisin captive in her apartment - couldn't happen to a nicer fella. He starts to panic tonight though when Katy orders him to tape a video confession of all the things he has done, and when Charlotte heads off to Spain, Oisin begins to really get worried for his safety. Also tonight, Robbie finds a way to keep Carol and Jack beyond Cathal's reach while Mondo’s attraction to Melanie provokes Kerri-Ann to intervene... again.
