The popular duo seemed set for a shock split earlier this week when Nancy (Jessica Fox) decided to move away to Canada, wrongly suspecting that Darren was cheating on her with Cindy Longford (Stephanie Waring).
However, the latest episode of the teen soap saw Nancy find out the real reason behind Darren's strange behaviour - before tying the knot with him in emotional scenes.
Digital Spy recently caught up with Ashley Taylor Dawson, who plays Darren, for an exclusive reaction chat about the wedding episode and where things go from here.
Are you glad that Darren and Nancy's wedding went ahead?
"I'm really glad. The whole storyline has been beautifully written. I really enjoyed the fact that it wasn't an obvious affair plot - instead it was just a case of Nancy getting things misconstrued.
"It's a real relief for Darren that the wedding has now gone ahead, especially as he has often worried that Nancy is too good for him. Darren was mortified when he realised that Nancy thought he'd been cheating on her with Cindy, as it had just been a massive misunderstanding between them."
Why do you think an unlikely pairing like Darren and Nancy work so well together?
"Well, Darren is a male chauvinistic pig and Nancy is a feminist, so you'd think that everything would be against them being together. But somehow opposites have attracted! I think Darren brings the best out of Nancy, while she brings him back to reality and gives him some organisation in his life - which he's definitely in need of.
"I think the characters work well together and they challenge each other all the time. It's quite comical, even when they're arguing. In many ways, Darren is a typical man and Nancy is a typical woman."
"I think that everything that Darren and Nancy have got in their relationship is quite serious, whereas the Darren and Cindy relationship was just sex, basically! Between those two, it was more of a raw attraction rather than something that would work well in the long-term. At the same time, I thought it was quite sweet that we revisited the Darren and Cindy relationship, because they have been through a lot together.
"But Darren has matured since then. Their recent goodbye scene was a great one to bring a bit of closure to what they had. I think it shows that Darren is strong and he does want to be with Nancy."
Why was it so important to Darren to have the wedding as a surprise?
"I think it was just typical Darren when he gets an idea in his head! He thought that it would be the best way to show Nancy that he loves her, rather than just doing the normal thing.
"Darren could have just surprised Nancy by taking her out for a nice meal, but his thinking is always a bit mental! He thought the gesture would be amazing. But he didn't really think about how much Nancy would have liked to organise things!"
What was it like to film the wedding?
"As you will have seen on screen, we filmed the wedding outside, so I was a bit worried that it would be a long and miserable day with bad weather! Luckily, it ended up being a nice day, although it was a bit windy. I enjoyed it - it was a nice group of people, so it was good fun to shoot."
"All of the feedback on Twitter has been lovely. Everyone seems to have really enjoyed the storyline and been caught up in it. I put that down to the writing and our new producer Emma Smithwick, as what she's been doing here has been great.
"I think what we're seeing now is that scenes are having time to breathe. Instead of just having quick little scenes and loads of stories, the viewers are able to invest in the characters more. There's time to empathise with everyone and see every side of the story, rather than just having quick scenes, which can be fun to watch but aren't as engaging."
Will married life change Nancy and Darren?
"I think the only way it will change them is by giving a bit of solidity to their relationship. It proves to both of them how much they mean to each other, so if anything, I think it will make them stronger.
"They both want the marriage and they want to be together, especially after everything they've been through to get to this point. Hopefully married life will help them to build on what they've already got."
"It's definitely something that they both want, as everything's going well. I think that's another reason why Darren went ahead with the surprise wedding - he's got the pub back, he feels like he's learned all his lessons, and he's come full circle. This time around, Darren doesn't want to mess anything up and wants to get everything right. Now that they're married, having children is something that they'll look at in the future."
In real life, you and your fiancée Karen welcomed the arrival of a baby boy last March. How are you finding fatherhood?
"It's the best thing that's ever happened to me. Every day is amazing as there's something new. He's such a good baby as well - he hardly ever cries, he eats well and sleeps well, so it's like having a little companion buzzing next to you. He's also got the best mum in the world!"
What's next for Darren and Nancy? Can we expect a happy few months on the way for them, or more drama?
"There's a lot of drama on the way and I've thoroughly enjoyed filming it. There's some very exciting stuff coming up, and it's some of the best material that I've had in a long time. I'm loving it."
