'Hollyoaks' 2012 spoilers: Nancy, Darren, Mercedes

Hollyoaks is airing a huge block of episodes this week as Warren's exit storyline reaches its climax - but for those already wondering what's ahead next year, we can now bring you a handful of teasers for 2012.

Darren Osborne (Ashley Taylor Dawson) will prepare to make the ultimate commitment to fiancée Nancy Hayton (Jessica Fox) in the New Year when he starts planning their wedding in secret.

The businessman decides that a surprise Valentine's Day ceremony would be the perfect romantic gesture for Nancy - but when he's tempted back to gambling, could he lose more than just his wedding fund?

Meanwhile, as Mercedes McQueen (Jennifer Metcalfe) tries to put her difficult 2011 behind her, Lynsey Nolan (Karen Hassan) becomes an unlikely friend and source of support.

Just when it seems like the drama for Mercedes could be over, a charming doctor arrives on the scene and shows her the benefits of 'selling her services'. Could it be that Mercedes hasn't learned her lesson at all, and will she be heading down a dark path?

Elsewhere in the village, it soon becomes apparent that sixth former George (Steven Roberts) is hiding a huge secret - but how long will he be able to keep it from his friends?

Also, as Brendan's son Declan (Jay Duffy) makes his return trip to the village, are Cheryl (Bronagh Waugh) and Lynsey right to be worried?

Hollyoaks airs weeknights at 6.30pm on Channel 4.
