Alley-Cat Quartermaster (слэш)

This all started with a conversation with my Queen of Plotbunnies and Paladin of Writer's-Block Slaying, MinMu: So many fics include Bond breaking into Q's flat. What if it was the other way around?
Summary: After the death of M, everything is in shambles. MI6 is trying to stay afloat and not let its enemies scent blood in the water; the new Quartermaster is orchestrating a flurry of activity to keep his branch at pique efficiency and therefore his agents alive; 007, the agent hit hardest by the death of the old M, is going through the motions and throwing himself into his work.
Everyone is a little bit broken, and a lot exhausted.
So when Bond and Q end up together in unexpected circumstances, perhaps the outcome should not be so unexpected...
