I think the inbetweener's James Buckley should replace Norman and Hattie in the future playing a rebooted "youthful" teenage Holly. My reasons are thus: He's offline and will require rebooting. When he reappears he's back to original specs with no memory of everything thats happened (ish). He'll be stroppy and teenage and gets things done very slowly and too readily up for taking risks. Holly, apart from Kryten, is the only actor who's changed and whose actor can feasibly change. The Normon Lovett thing is a whole ugly can of worms. Going back to Hattie would just make more obvious above can of worms. So what do you think? I think Buckley has the ability and the similarity to Norman to pull it off. Also it'll add something new to the mix (not a bad thing) and give it a youthful quality.
