At first, Dean is worried about his mum's reappearance. But he's relieved when Karen reveals she has been discharged from hospital and is still taking her medication, and plans to stick around for a while.

However, there are a couple of small problems to handle. Dean still hasn't told Karen about either Ziggy or the discovery he has a half-sister, Mackenzie Booth (Emily Weir) who now lives in the Bay too!

When will there be a good time to break the news? And how might Karen react to the bombshell that Dean's been back in touch with his estranged dad Rick Booth too?
