Hoping the casting for the students gets announced soon, will give a better idea of what years they're focussing on. Instagram has helped me to work out some of them but they're all on the older side, which makes sense with it being instagram.
There could be a few kids from the children/siblings of students in the earlier series. There's lots of opportunity here.
- Izzie Charles (Chlo and Donte's daughter) would be 12/13 now. She may also have a sibling.
- Lauren Drummond seems to be free at the moment and I expect she will return as Mika. I think Thomas Payne might be living in America so they will have to recast for a Brett return. Brett and Mika could've easily had a child within the couple of years after they left, although I imagine they would've been born after Chlo left or the baby would've been mentioned. Mika and Brett's child could be in year 7/8 now.
- Cheryl Bryant (Janeece's daughter) would be around 12.
- Prince Kelly (Sam, Denzil and Earl's little brother) would be 15/16/17. I wonder if the school will still have a 6th form.
- Dannielle Harker could return as a businesswoman with a couple of kids, one in primary school and the other starting at WR. I's watching the original run on Iplayer at the moment and am loving Danielle.
- Kim has a son (now 12/13) so I imagine he will appear in the new series. I know Kim 'adopted' another child in Rwanda but I think she was taken back there by her biological father.
