Okay so lots of speculations that Scott could be leaving soon. Whether or not that be true, he's gonna leave sooner or later, and he probably won't be taking Chris Stark with him.
SO what's gonna happen with Chris? Most likely option maybe is co-hosting with Alice, given Chris never having done a show by himself before and Alice being a good co-presenter as proved by history.
Another idea: Chris doing a similar show to something like Cel did on a weekend? Something to do with viral videos, trending music or something similar, being as he went viral thanks to Mila Kunis and all that. (He's a perfectly good radio presenter in his own right, but that MIla Kunis video will always be there.)
Maybe an hour long show or something completely by himself, just to get him into the groove of driving the desk himself etc? Then after he's become skilled with that, then move him up as a solo presenter?
Unless, of course, Chris does leave with Scott being as they've always been a partnership, then he goes into some online or maybe BBC iPlayer stuff for Radio 1 being as they're obsessed with YouTube, maybe like the ICYMI shows he did?
Or Chris could leave R1 altogether and go to another station. Personally I wouldn't do that, his dream job was to be at R1 so unless that's changed in the time he's been there he'll stick around as much as possible.
