I don't know what to tell you other than he's still in the UK and hoping to be back in the fat suit on the 19th. And jet lag from the UK to the US is a breeze, gaining five hours is a lot easier to deal with than losing them. Or at least I think so. I would see no problem, if he was fully recovered, in arriving one day and going on the next.
Nothing precious, plain to see, don't make a fuss over me. Not loud, not soft, but somewhere inbetween. Say sorry, just let it be the word you mean.
