The Diary of John Watson:
All of this is gnawing at my mind. I am so confused about how I feel about everything, and I just can't sort out what I'm feeling anymore. I need to figure out all this shit about Sherlock. I can't even be in the same room with him anymore without my head exploding. I need to figure this out - it can't continue like this. Okay, this is what I know.
When I'm with him, I get warm and flushed
When I'm with him everything lights up and everything dull and mundane seems brighter somehow
When I'm with him my hands get sweaty and it feels like every part of my body is alight
Recently there seems to be discontinuation between us. It's like we're seeing each other through smoke or smog.
Conclusion: Sherlock is a dragon.
