John and Lestrade knew each other before they met the Holmes brothers.

They both used to work in the same strip club to pay for expenses not covered by their scholarships.

They were even lovers for a while, before deciding they worked better as friends.

Now the two friends are helping each other to snag the Holmes Brother of their dreams.

Which may take a while, because for all their intellect, the Holmes boys are notoriously thick when it comes to matters of the heart.
