star William Beck has opened up about the situation his character Dylan Keogh has found himself in on the long running medical drama thanks to the actions of his mentee Jodie Whyte (played by Anna Chell) as he receives huge news from girlfriend Sophia Peters (Kellie Shirley).

The young medic slept with a man called Aaron, who is the husband of a woman who died as Dylan and Jodie helped her give birth after her car crashed into a restaurant.

During their dalliance, she appeared to imply Dylan had a choice as to whether to save the mother as well as the child, leaving Aaron fuming, and he later reported Dylan for what he perceived to be his error of medical judgement.

Speaking exclusively to about the repercussions for Dylan, which ramp up hugely this week as girlfriend Sophia tells him she is pregnant and he is arrested, William said he doesn't blame "guileless" Jodie and says Dylan may have to rethink how he deals with things.

"If I reflect on it all I would imagine that he is probably, it's not said with amusement, but I think he would be thinking, 'you see, this is what you get for trying to help someone'. Jodie's guileless. Dylan can see that there's nothing to blame her for there."

With his career possibly hanging in the balance as the police become invovled he has a brief respite when girlfriend Sophia tells him she is pregnant. While his reaction may seem to be rather matter of fact William says that in fact he sees this as a good thing.

"I think this really quickly in that moment with Sophia (when she tells him the news), I do think he thinks, 'Oh, we've got something good', but she doesn't hear it like that," he admits.

"I think he probably would have viewed the prospect of being a dad as of being out of reach and but there's kind of a melancholy about it for him. On top of that, he's obviously got a hugely troubled relationship with his own dad. Dylan, being Dylan, he would have wanted to have remedied that or or something.

"So I think in his response to being told (the news) there's almost a triptych of reactions. There's the one that says, 'Really?' There's one that says - very practically - 'Is it mine?' And then there's one that's kind of, 'Oh my god, that's amazing'.

"Of course, Sophia responds to what she thinks she sees, and to my mind, I think that's so true to life. People who have to deal with news like that or an event like that before they're expecting it. It's so easy for that communication to break down," he said.

The fact Dylan and Sophia's relationsip has endured this long may come as a surprise to many but William feels they are a good match. "I think the relationship between Dylan and Sophia is authentic in the sense that I'm not sure they know where it's going," he said. "I think they're both people that approach life and other people relationships, certainly, with a great deal of caution.

"And that's certainly about to change, because I think he's obliged suddenly to realise, once again, that whether or not he believes himself to be right, there are emotional consequences for other people that mean that maybe that's not important.

"Maybe maybe he's going to have to stick up for himself in a practical sense, and maybe make the best of the job, rather than try to obtain a kind of a perfect logical truth. And he's hit twice in quick succession by a very, very abrupt confirmations of that feeling.

"I think over the next couple of episodes you see him kind of just winded and unable almost to speak for himself, because just the juxtaposition of what he thinks is the right thing or what should be happening, and yet what is clearly happening before his eyes is just it's unbelievable."
