Watson's POV.
-------
He does not like to speak of it. I have attempted to breech the subject countless times, and he does not seem to care.
I am not sure which alarms me more.
Sometimes I want to take him by the shoulders and shout in his face, "I betrayed you! I have left you alone, when I swore I never would!"
"And did you really think that I would care?" I imagine him answering me, sneering. But I have not done this, perhaps because although I know his true strength, he seems so fragile.
My guilt, then, is without any resolution.
