"Hate you?" he exclaimed in disbelief. He had not expected that as an opening to this conversation. "Marian, you have made me feel many things over the years, but I could never, ever hate you." Not even when he thought she was marrying Gisborne had he felt that-- heartbreak, intense heartbreak, and the greatest disappointment of his life; but still not hatred, not remotely.
That was not to say that he was particularly fond of things she had done, in the false world or in the real one, but neither would she be of things she neither knew about from before... or of things he needed to confess to now.
He glanced downward, as she had done. "And besides, you're not the only one who was given actions that they regret." Knowing it would hurt her to know what his other self had been like, he nonetheless had to tell her. Peering up without raising his head any more than he had to, he said quietly, "I was... with... a couple of women. One during that situation, and I had a past with others."
There was no way that he could look at her when he told her what he was about to. "I discovered that I had a son. I hadn't known at the start, but... for a few days, I had a little boy."
It physically hurt to think of that. None of what had happened had been real, and yet it had been. It had felt so real, and having that go away was just as painful as losing it.
