I was pretty certain it would turn out to be Darren after Denise asked if Darren had got engaged to Libby because he had knocked her up. Bit of irony there, with him having knocked someone else up instead. Also, as he was the last to leave for the hospital I thought it tied in well, especially with the spoiler about the father taking one look at George and running off. I did wonder after Thursday's too, with Heather describing a businessman in a jacket - Darren likes to get a bit ahead of himself where that's concerned. There was the comment about the tiny bit of stubble or something too, and I think it was about January/February time that Darren was wanting to look older.
I'm disappointed too, Darren's the one that I least wanted it to be. I wish it was Minty but he was the least likely out of all of them.
