I think something will happen to do with 11ths things he liked that 12 doesnt. Perhaps seeing the bow tie amd ripping it off or saying he cant stand Tommy Cooper's sense of humour. It would be a biy difficult for 12 to be offered fish fingers and custard for a meal and pull a face and say yuk. What would be more clever, and more in keeping; if 12 looks at himself in the mirror and say I dont hate bow ties, but that really isnt me, etc.. Then later on there will be occasion for 12 to don a bow tie and we could see him put it on and give a little smile. I can see Peter Capaldi doing something like that.... and it makes me feel all warm inside
