oh, my angst-loving heart I don't entirely love the episode, and I don't trust that they'll follow through AT ALL. but the more I think about it, the more juicy tragic facets I find.
1. "I needed you." O. M. G. oh watson ymmv, but for me, this is the culmination of three years of Joan denying, refuting, burying, ignoring, and fearing the repercussions of dependency. This is being kidnapped and Mycroft and London and Andrew and the relapse and Shinwell, and her struggle not to feel responsible for every damn thing, and she was doing it, they stood together against Morland and Sherlock trusted her to take the lead even, he trusts her more than anyone, and then it started to crumble and she doesn't understand why so kept going on, it's the work that sustains, that will bring them together, it's the thing they share, the basis and foundation for everything.
She thought it was that all-too-familiar combination of his arrogance and insecurity prompting the self-centered questioning about her commitment [at the start of s5], again. And she thought she'd given him the answers he sought that time, reassured him she was where she wanted to be. But he kept on doubting. Doubting Shinwell, his determination, his ability and intelligence, and by extension hers. It never went away, even when he threw himself into the mix and took over. She let him, hoping he would see what she did, recognize Shinwell's determination and strength. His acts of penance. And none of it was enough. She didn't know if he believed her lie, that she didn’t feel responsible for Shinwell’s murder; at first she believed it herself: it wasn't her fault. She was angry. But of course it could be both, and she did do this, it was her mistake, and she needed him and he wasn't there. 2. That moment of bare vulnerability when he admits, "I forgot," and her wrath blisters the ground between them. I think this is the single most tragic moment between the two of them, in five years: how much they each need the other and are both utterly unable to perceive it, let alone bridge the chasm. They both made the same mistake. Er, not falling in love but of holding back, hiding their fears until they combusted. 3. "I'm the part of you that wants to get better. Who else would I look like?" WHO ELSE?!? WHO ELSE? "[People who love each other] make promises." I'm gonna make sure you're ready when the time comes. I promise. He wanted this to be Watson helping. Watson holding his hand when he's scared. Watson the person who knows him better than anyone, who wants him to be better, who makes him better. This is the most baldly romantic declaration since the proposal, and of course Doherty has to bury it underneath layers of distraction and deflection and disguise, but I don't care. For all his boring noromo protestations, he's totally a shipper. 4. I don't know if I can write this (feel free to use this as a prompt, anyone), but my headcanon is that Watson jumps to the conclusion that the wreck of Sherlock's room is evidence of Tyus Wilcox's final retaliation against her, and when she runs out of the kitchen, it's to track down the last remnants of SBK loyal to him and burn them to the ground and herself with them.
