Lacey was a lovely person to chat to and her passion for the show and her character really shone through. There'll be many who'll be sad to see her go this Christmas, but at least it sounds like we have plenty of festive drama to look forward to in the coming days.
If you haven't already done so, click here to read the main part of our chat with Lacey, in which she talks about Stacey's relationship with Ryan and the character's departure.
Alternatively, read on for some bonus bits from the Walford favourite…
What has Neil McDermott been like to work with on this Stacey and Ryan storyline?
"He's been fantastic. From the minute he came in, I really thought that Neil was a great actor. I've enjoyed working with him and I think we work well together. It's been nice because I've often worked with a lot of the same people, so it's great to start working with someone new. You build up a rapport and then you know what the other person's going to do to a certain extent. He's such a nice man, I can't tell you - he's really lovely and a great actor."
Can you name any particular highlights from your time at EastEnders?
"I've enjoyed every storyline I've done, but particularly the bipolar one. That one allowed me to learn more and it had a really great reaction. There were lots of people who watched those episodes and realised that they had bipolar themselves. That meant a lot to me - that people had watched it, taken information and learned from it. I think it's so great that EastEnders can do things like that - they show things that do happen in real life and they help people. And also, working with Gillian Wright on that storyline was just fantastic - because she is a fantastic actress. I learned so much from her. So the bipolar storyline was one in particular that I felt honoured to do."
Would you say that your storylines this year have been particularly strong? The Stacey and Archie reveal in the live episode was certainly memorable!
"Yeah, I never saw that coming! Not even on the day! I'd made my whole family put bets on Sean! I was so convinced that it was Sean! That was another time where they trusted me with such a massive thing. And being involved in the live episode was a once-in-a-lifetime thing - it's such a huge cast and it's like a huge machine here, so the fact that it ran so smoothly was great. I felt very proud to be part of that - and to be able to achieve that as a team felt really good."
"I wasn't well at all! I hadn't spoken for two days - I was told that I wasn't allowed to speak for two days because I'd lost my voice. Everything had just closed in my throat, but five minutes before the live episode, I thought to myself that I'd just have to be naughty and just speak. I was so scared that I was going to open my mouth when it came to my line and that nothing would come out! So before the episode I had to test my voice out, and fortunately something did come out! In the actual episode, I managed to last the full half an hour, but I had nothing left after that for a couple of days."
Did being ill make it difficult to prepare for the live episode?
"Well, I was sent home from one rehearsal because I was unwell, and I felt like I didn't know the script. I didn't know that Stacey was Archie's killer then, but now I know why they were so scared and so quick to get me to the doctor! But then, I didn't even know whether it would matter whether I was in it or not!"
Are you glad that Shane and Jessie have been back for your final months on screen?
"Yeah, it's nice to have them back. They're such big, bubbly characters - both the characters and Jessie and Shane themselves. They're a lot of fun and they're so good at playing the characters that they play - nobody could play them like they do, so it's great to have them back."
"Yeah, definitely! She's brought the little party girl out in Stacey, and the mouthy, upbeat and fun side of her after all the dark years that she's had."
How have you found playing Stacey since she became a mother?
"It's definitely been different as an actress. One thing is that it's like suddenly having another prop - it's not just you, because you have to constantly think about where the baby's going to be all the time! And you constantly have a pram, or a dummy or something else! It's different because, without a baby, you have a lot more freedom to do what you want. But it's also really nice to have the baby when you're filming. It's also been good to show how someone so young can be a mother - as it happens a lot."
Do you think EastEnders can carry on going from strength to strength in the months ahead?
"Yeah, I hope so! The show's had a bit of a revamp and it's getting better and better. I hope it carries on doing really well."
Can you tell us anything about your future plans?
"I don't make plans - I don't like them! (Laughs) I've got Being Human coming out in January, but I just like to take each day as it comes and see what happens."
Finally, is there anything you'd like to say to the EastEnders fans who've supported you over the years?
"Yeah - I can't thank them enough! They've made Stacey who she is and they've helped me so much. When people write in and they're supporting you, it's just life-changing. Without those people, there wouldn't be a programme and there certainly wouldn't be a Stacey, so I can't thank them enough. I'm forever grateful for the support they've given me."
