Wow, what an amazing group this is! I so wish I had found this place a few years earlier than I did!
I haven't thought about where Chryed might be in much detail (it's because I spend too much time on YT watching Chryed clips, lol) but here are a few thoughts about what might have happened/be happening:
-I think they stayed in Florida for several months, with maybe a trip to New Orleans, if they were around until Mardi Gras. I hope they went to Key West, had a blast,and bought another of the Key West zip code tee shirts, so that they now each have one, lol.
-I'm sure Sy got on well with Linda. After meeting Zainab back at Christmas 2008 at Ian and Jane's house, I'm sure she found him to be an absolute pussycat in comparison, no matter what she knows about Chryed's problems, lol.
-I think the boys spent a lot of time just being together, trying to get over the pain and hurt of the previous months, knowing that if they work at it, they should be okay. Sy still has a lot of guilt, but he's taking Tanya's advice, hoping that eventually Christian will forgive him for cheating.
-When they go back to the UK I imagine they sneak into Walford to rent a van and pick up their stuff that the Masoods have been storing for them ( BTW- whatever happened to Christian's toy chest???

) and then head to Birmingham where Amira and new hubby have rented a flat for them. Of course they cannot wait to see their little princess Yasmin again! I hope she has stopped picking her nose!
-As for work, I see Sy getting away from business, finally realizing how rubbish he is at it, lol, and maybe getting a job at a college as a teaching assistant ( isn't he supposed to have an economics degree?) This will give them some regular income so they can work on paying back Mas and Zee. If that proves too boring for him, he can go on to something else. Maybe he will do some masseur work, too, to bring in extra money and pay off the debts quicker. Christian will likely go back to working at a gym or as a trainer, but I see them maybe planning on opening their own little catering business, more like the original Fit for a Queen business that Christian and Ian and Jane started. The business will of course be located in the Gay Village of Birmingham.
-They are happy and content, spending as much time as they can with Yasmin. They may still decide to adopt a child, but only when both of them are ready.
-And of course, as others have already noted, they have the big sofa back!!!! They spend much time on this sofa, cuddled up together, with hot chocolate and custard creams.
