A Holmes/ Watson fic

[hagstrom]

Hello everyone!

I'd like to find this fic, post-Reichenbach if I remember correctly, where Watson and Holmes have a conversation about love and Holmes says he wishes to be sure of someone. Later, I can't remember how or why, Holmes repeats the phrase (I wish to be sure of you) and Watson understands the detective is in love with him It's all canon verse
Also, I think Watson has a child and Mary is dead.
Thanks in advance!
