Okie doke.To be honest it kind of makes sense. Benedict is a good actor and they may be able to do double shoots of DW and Sherlock at the same time to save money
I can't see how they would introduce the master again though considering his predicament last time we saw him. If ever there were an award from slipping out of the clutches of death in weird ways it would be him. It would be weird seeing Benedict essentially playing Moriarity, though
