My William,
Another case solved is another job well done. You came by the lab immediately after to share your findings with me. I have always been in awe over how your mind works, putting the pieces together so quickly. I love how enthusiastic you get over your cases, the passion sparkling in your eyes as you talk about them. You had also stressed to me how you couldn't find your paperwork from your last experiment, as you tend to leave them lying about the flat. I found them and also found a way to solve this problem of disorganization for you. So, you should find a field notes journal to keep track of them on your bedside table.
Sherlock, you will never be unlovable to me. There is not a thing, person or powerful force that could ever stop me from loving you. I would say that you have stolen my heart, but is it truly stealing if it has been given to you? I trust you to keep my heart safe, to never betray it; I know you would never do anything to endanger it. I hope you trust me to do the same.
We discussed (and argued about) my wanting to go with you the next time you visit Eurus. I know you're still scared, but you'll be with me; we don't even have to be there for long. The truth of the matter is, regardless of what she did to us, I forgive her. Yes, it was painful and not at all the way things were supposed to happen, but look where we are now. You can't have sunshine without the rain. I know she has done awful, terrible things but she is still your sister. If I am to be in this family as you have so often said you wanted, shouldn't I at least meet her? If you don't want me to, I won't, but I promise there is no reason to be afraid. If you want a third opinion, maybe we should see what Mycroft thinks about this. If he agrees with you, then I'll drop it.
On the bright side—at least for me—Christmas is in two weeks. I know it's not your favourite time of year but I'm sure you'll enjoy it more than you used to. I do look forward to going to your parents' home for the holidays. Your mum is already coordinating baked goods with me. She'll be making ginger nuts, as they are your favourite. I've decided to bake my mum's chai sugar cookies with cinnamon eggnog icing. They're my personal favourite holiday treat. I'm not sure what your stance on eggnog is, but hopefully you'll like them.
I love you so much, Sherlock. I hope you and I can work things out. I don't want us to fight anymore. Even though we're a bit frustrated with one another, I'm glad we don't allow it to interfere with our affections. We'll make it past this no matter the verdict. I'll make sure to cover you with kisses when you come home.
With all my love,
Your honeybee xxx
Author's Note: Where do y'all stand on their disagreement? I personally think it's an important step for Molly to meet Eurus at least once.
p.s. please be kind with your answer, whichever side you're on.
