No it doesn't Adam, you don't know anymore than I do whether Nevill took his watch off in the kitchen every evening or just that evening or not. Your are making assumptions as usual.
Come on Maggie. Even by you're standards you're earlier post was pathetic.
Saying the watch was on the work surface but still somehow ended up bloodstained, damaged and on the floor is complete unsourced rubbish.
Why would Nevill get ready for bed & then take his watch downstairs to the kitchen ?
Anyway it makes no difference. The bloodstained, damaged and on the floor watch convincingly highlights a kitchen fight.
My post above shows the watch also matches Nevill's bruised wrists and forearms and broken rifle butt. Which is 'sourced' information.
