Yeah we definitely need more characters back that would have great potential, like Penny, and also Stacey needs Martin, lets be honest. They work so well as a couple, apart from the night she had with Max, and when they split up in 2018 she was all over the place and clearly unhappy. She loves Martin and he loves her. He even admitted it to Sonia when they were on a 'date'. I have always hated Martin and Sonia together and i think Martin and Stacey suit each other a lot more. I always feel like Sonia is too old for Martin even though they are the same age haha.
I really hope the writers don't just put Stacey with Max just because Ruby and Martin slept together. I feel like Max and Stacey are too toxic. I hope they do put Martin and Stacey back together but build it up slowly so they start off as friends and then slowly go on dates and get back together because otherwise they will just break up again.
It really annoys me how the writers always split Martin and Stacey up because they are a great couple and honestly Ruby and Martin are horrible together. They are so cringey and just don't work together and if they do end up together, Martin will want to settle down but Ruby will use him like she did with Max and want an open relationship, which Martin won't want and then he will realise he belongs with Stacey
