Joan smiles at that, too. When she had been actively seeking to adopt, she had assured Sherlock that she would take care of everything, and Sherlock had offered to leave the Brownstone, to give Joan and the child the whole place free from his unusual influences. She had turned down the offer firmly. She would never kick Sherlock out of his home, and there's so much a child could learn from him, even if Sherlock himself is uncertain about whether he had anything of value to offer. So to hear him say he wants to be part of Henry's life...it warms her too.

She looks over at Ted, and the expression of happiness on his face is so wonderful that her own smile widens, feeling a deep happiness as well, even in the midst of her sorrow.
