Notes/Warnings: Written for this prompt on sherlockbbc_fic.  Warnings for incest, and Greg and Molly being really incredibly dense.  They got a nice date out of it?
Excerpt: That was Mycroft Holmes sitting a few tables away; Greg would know him anywhere. It wasn’t his presence in itself that was so surprising; this might not have been Greg’s kind of place, but it had to be Mycroft’s. The surprise lay in the fact that he had a woman with him and Greg had been reasonably sure that Mycroft was gay. Gayer than picnic basket. Gayer than Christmas. Gayer than… something really very gay.
