Eyes Meet Eyes (слэш)

It's a dying thing, to have a soulname. Something left in the dark ages of man's tortured past. But John looks at the mirror and thinks a name he dares not voice and sometimes he thinks that maybe, just maybe, there's someone else out there thinking a name as well, and it goes together for them. He doesn't tell Sherlock. He hints to Greg. He panics when a voice at the pool sounds like the one he imagined thinking back all those years.
