Jake and Antony have always had a rougher, more intense relationship than that...and Jake's getting tired of fighting for something more. Which Antony senses. It's added a lovely undercurrent to the whole story. What had begun to feel like a placid stream now has danger lurking under the surface; not just to Jake as he digs into Owen's disappearance, but also to the life he and Antony share.
It's changed the ending a bit. And made me understand why I did some things I did in it. And lengthened the story some. Right now I have 67,000 words in the connected part and 40,000+ in the ending bit, though a lot of that will now go by the wayside. My ending will be much simpler. Not so much rushing around. And much more evil in the most banal of ways.
...once I let him.
