These are wonderful. Somehow I had never thought of Brian kissing Justin while he's unconscious, but I could see it happening (and it gives me the shivers). Another thing I could see happening is Brian trying to hide the worst of the cancer from Justin, and Justin forcing his way in anyway.
Loved this line:
Then Brian joined him, kissing him instead of cursing him, and Justin realized how good it felt not to be fighting alone.
and this one:
A thousand sarcastic replies ran through Brian’s mind, but he could still taste Justin on his lips. He didn’t say a word, just kissed him again before the rain could wash it away.
