My apologies, it's not quite six AM here.  The posting scheduled in this RP is a little erratic, and I haven't picked up what timezone everyone is in yet.  

But all I meant to say was that if he hasn't responded to you in 24 hours already, it's dangerous to stop the action this early in an RP's development on account of one individual.

Give him a reasonable opportunity to get involved, but frankly, you've waited a long time as it is.  It would be better to abort the arc before it begins than to get stuck in the middle of it, and hold up progress of the rest of the RP.  

Like I said, its still early.  The two of you, if he returns, will have plenty of time to have a Shadow Game.
