Lewis has a history of being a crap cook. Hathaway is supposed to have the ability.
Pierce and ping
I'm still holding out for a few one off episodes I think they'll leave next weeks episode with both Lewis & Hathaway still un-decided so if it doesn't come back we can assume Robbie & Laura are living happily ever after and James is doing whatever he wishes either an inspector or having left the police force but if it does they are both still employed
I do think it'll we depend on Laurence's American dream if it works they'll be no more if it doesn't the show will be back January 2015
