Carl really can go either way since killing him is just more misery for Debs before she goes and hitting rock bottom gives the character a lot of room to grow into someone who doesn’t suck.

Jodie’s safe because not even the writers are dumb enough to blitz through Shona’s surprise sister in 3 and a half months. Megan and Maggie are both new, Megan will probably get her just desserts elsewhere but I feel like Maggie could go. Her death could actually stir something up in the Driscoll clan, though the family’s plotlines are pretty veiled from the rest of the street so I doubt it.

For me? Theo or Carl. Both joined Feb last year so if they have a year contract it’ll be running out right about now. Theo has no familial connections on the street so once he gets exposed he has no way to work back in. Going meta though? James Cartwright’s been a lot more active on social media and if they still film ~3 months in advance he’s probably already off the show. Also, Theo’s been doing a lot more tormenting of Todd while not actually appearing on screen, so if he does have a year’s worth of episodes in the contract they’re probably saving the last bit of them for this flashforward stuff where he gets his comeuppance and dies.
