The doctor is upset not exactly because of he still cant find Melody, its becasue he knows how she dies, anyone remember Silence in the Library/Forest of the Dead. He has to keep Rivers death a secret now, not just to River, but to Amy and Rory.

I totally forgot about this.
Karen Gillan : “The Biggest Twist so far is yet to come”
Matt Smith : “Alot of Questions are answered in the remaining 6 episodes as well as asking some more along the way”
Steven Moffat : “yes! You know the secret about River, or do you? “
Arthur Darvill : “I can’t say how involved we are next year but I think the last 6 episodes are some of the best we have ever done”
