I hate to say it, but considering he didnt ask for an extension of the turn there is really no reason to expect an 8 hour delay to make any difference. Obviously it could pottentially make a difference but if he has neglected submitting his turn up to this point I just dont see that 8 hours will mean much in the end when it wasnt requested.
It may be a good idea to go ahead and look for a sub, then if Bluff doesnt come back or acknowladges in the thread that he is having Real life problems and needs one then we are a step ahead of the game. And on the otherhand if you find a sub and he does come back and get his turns in on time then you can kindly thank the sub and let him know you will keep him in mind in the future if we need him.
I'm guessing with the current stale situation though that we are more inclined to need the sub than not to need one though.
It's a shame though I was hoping to see the turn before I went to bed
