When Natasha's arms wrap around her, Yelena feels herself crumble against her, turning her face into her sister's shoulder. She doesn't bother holding it at bay, and she isn't sure she could if she tried, not now, not like this. So instead, she just lets it all out, heaving sobs, ugly tears and all.

And it is so much more than just this mysterious return of her sister, or the loss of her, that is finally hitting. It's learning she was, at best, adopted, and at worse, just a mission to the people she called family for the earliest memories of her life; it's all those years of trauma under Dreykov; it's the way she has never even started processing her own death in The Snap and how much everything changed in those seconds-years.

All those things she has bottled up for far too long, finally have the chance to escape. And there's no one better suited to receive it all.
