Concerned for Ryan (Sol Heras) following his heartbreak over Tracy Barlow, Sophie joins him as he heads out into town. However, it's not long before Michelle's troubled son falls back into old habits as he scores some coke to make himself feel better.
Later, when a drugged-up Ryan walks out onto a busy road and finds himself in danger, a horrified Sophie makes a desperate attempt to get him to safety - only to be knocked down by a car herself.
Sophie is soon rushed to hospital for emergency medical attention, and the aftermath of the accident sees her informed that she may never walk again…
Digital Spy recently caught up with Brooke Vincent, who plays Sophie, to hear all about the storyline and life at Corrie.
How have you found filming this big storyline for Sophie?
"It's one of those storylines where you read the scripts for it and you think, 'Oh my God!' As soon as I heard about it, I started thinking about how I was going to play it. I had a perception in my head about how we'd film it and what the shots would be like, but once everyone got going, it turned out to be completely different from what I imagined it to be. It's actually been better than I expected.
"It's been a challenging storyline for me because I don't know anybody in this situation - having a spinal injury and being told that you might never walk again. It's not like my lesbian storyline where I knew lesbians in real life and could ask, 'Am I doing this right?' I've just got to trust the writers with what they've given me."
Did Corrie warn you about the storyline quite far in advance so that you could do research?
"Well, when I first got the scripts I wasn't sure exactly what Sophie's injuries were going to be. I'd had a meeting and I knew all about the actual accident, but I didn't know exactly what would happen next, other than that Sophie mightn't be able to walk again.
"Since finding out about Sophie's actual injuries, I've met a lovely guy called Jamie Rhind from the Spinal Injuries Association (SIA), who uses a wheelchair after being in an accident when he was 19. I spoke to him about his experience, and we've also got a physio on set who's been advising us on what we should and shouldn't be doing."
What was it like to film the actual accident scene on the road?
"It was really exciting. We had a stuntwoman for the actual accident but I also did quite a bit of filming on the road. I say this all the time, but for me your natural reaction when a car is coming towards you is to move, whereas here they're telling you to walk in front of it! It takes a bit of getting used to.
"I always get a little buzz when we're away from Corrie anyway, because you're on-location and it's a bit exciting. It's really good and it feels like everyone works together more when we're out on-location. We're not on the set so we haven't got all the usual facilities, so it's just a really nice atmosphere as we all pull together to make it work."
How is Sophie going to cope with the aftermath of the accident as she hopes to start walking again?
"Sophie's a feisty character. She's one of those people who if someone tells her that she can't do something - in this case that she can't walk - she'll do everything in her power to do it.
"You'll see a journey for her and there'll be ups, downs and some frustrations. I think it's really nice the way they've written it, because they haven't forgotten that she is only young and there's things that she wants to be doing but she struggles to do them."
What have you learned from doing the storyline so far?
"Well, the other day I had to have splints on my legs, which helps to make the scenes look more realistic. They go under my clothes, but when I sat down and put these splints on, I couldn't get up afterwards. I've had also numerous people take me to the toilet just to pick me back up off the toilet, because I can't do it myself when I have the splints on.
"Really what it's taught me is that you take so much for granted when you can walk. Everyone just thinks that's a normal part of everyday life, but if you take it away, it makes you really appreciate what you have actually got."
Will Sophie be able to easily forgive Ryan for causing this mess?
"Yeah, Sophie's a Christian so she'll forgive anyone! But what she tells Ryan is that the accident has happened for a reason - it can't be for nothing. The fact that Sophie's in hospital is because Ryan was taking drugs, so now he needs to stop. For Sophie, this is the sign that shows Ryan needs to change his ways."
Earlier in the year, the newspapers all said that Sophie would become addicted to drugs. Were you disappointed when that rumour turned out to be untrue?
"No, because I knew it wasn't going to be true! The papers make up all these stories and everyone gets excited, but it was never going to be me.
"For me, the important thing is that we're putting a story out there which shows that drugs aren't a good thing. I think that's the main issue, whether I'm the one doing it or someone else."
Will Sophie's problems bring Sally and Kevin back together again?
"I hope so! Sophie certainly wants her family to get back together again, so hopefully that's what will happen. Who knows?"
Lloyd's daughter Jenna will be assigned as Sophie's physiotherapist. Does she do a good job with Sophie?
"Yeah, Jenna brings some light to the situation for Sophie - she knows what she's talking about, and she knows what Sophie should be doing. They get on well together, too - they have a laugh and a giggle. Jenna's a really nice physio for Sophie to work with."
Will this be a long-running storyline for Sophie, or will there be a speedy soap recovery?
"I think Sophie's physiotherapy will be long-running. It's a struggle, and the journey that she's going on to start walking without any help will be a long process.
"Soaps are soaps so we might have to speed it up a little bit as the story continues, but every situation is different. There'll be so many people sitting at home saying, 'Well I didn't do that', or 'This didn't happen to my friend'. But Jamie, who I met recently, told me that there was a lad who had the same injuries as him at the same time, and he was able to recover and walk out of the hospital. Each story is different, and we'll have to wait and see how things turn out for Sophie."
Are you glad that Sophie is getting a new love interest?
"Yeah, I am! I think my main issue was that not every storyline for Sophie needed to be about her sexuality. But to know that there'll be a new girlfriend for Sophie now is obviously really exciting.
"I can't reveal who it will be, but at the moment, it's more of a love interest than an actual girlfriend and we'll have to see how it goes."
Sophie and Sian had a huge fanbase. Do you think those fans are ready to see Sophie with someone new now?
"No, I don't think they'll ever be completely ready to be honest. Our fanbase was very much for the both of us and the support that we've had from people on Twitter is amazing. There's fanpages and there's people who tweet us all the time.
"But even though Sacha's character has gone, it doesn't take away the work that we did together. We've both had that time of our lives where we did that work together, and for it to have so many fans is a massive accomplishment more than anything.
"I remember when Nikki Patel, who played Amber, had people on Twitter saying things about her and I thought that wasn't right, because Sophie and Sian were never going to last forever as Sacha wanted to leave. People have to understand that stories have to go on and things change."
Will the Websters be busy at Christmas this year?
"No, it's not us this year! It's not our family. Nick, Leanne, Carla, Peter, Fiz, Tyrone and Kirsty have got big stuff coming up at Christmas. But no Sophie Webster!"
Most fans will know that you visited Kenya this year. Is that an experience that has stayed with you?
"Oh my God, yeah. Every time I look at the pictures, I just smile because it's the best thing that I ever did. When my sister or little cousins or nephews kick off because 'this toy isn't right' or silly things like that, I just say to them, 'They don't have all this in Kenya'.
"It's crazy. To me, they're so far away from the world that we live in. It was just an amazing experience for me to see it, and I'd go back any day."
Cast members like yourself have stuck with Corrie for a long time. What is it about Corrie that keeps you so happy there?
"The main thing is that we're all like a family here. It doesn't matter what department you're in, who you are, what you look like, whether you're male or female - everyone gets on.
"As I'm talking to you now, we've just all been in the green room and there's so many different types of people, interests and age groups, and different conversations flying about, but everyone just feels at home. I think that's the nicest thing about working here."
