He'd seen Molly discussing Moriarty with someone, and really couldn't have cared to get involved. He'd already put his feelings with Moriarty behind him. Why dredge up the past again and again? "No, she has enough on her mind." He didn't want to add his own issues to her plate. He wanted desperately to be able to take care of her, but during the week he was at work until the late hours of the night.
"I don't know." He finally decided to elaborate a bit, confide in the woman for the first time. "Reached bottom for a while here after Sherlock was.." The word killed was still difficult to place, and especially in Florence's home. "Murdered. Tried to end my own life several times, bu Florence wouldn't allow it. Florence and Rose, neither one of them left me though they could have easily turned their backs on me at the time.." He looked into the tea and frowned a little. "There was a time I wouldn't leave our flat. They stayed with me though I told them both to leave." And then he stopped talking again, he hated how low he'd sunk there. He needed Mary to understand the depths of his loyalty. Why he chose them. He looked at Ava for a moment, and his expression briefly softened.
"I'd thought there was no hope. No reason to go on. I'd watched Sherlock die twice, and my hope went with him. This is supposed to be a place of second chances. But mine had been stolen away. They brought it back. Those two. Three." He corrected as he looked up at her. He had a life beyond Sherlock, and he could now for the first time actually see it. He wanted her to know that he could.
