Cassandra has become something of a permanent fixture in Yelena's life in Etraya, the idea of not inviting her to this never even touched her mind at all. She's young, but Yelena knows a few things about her history now. And the giving of comfort is not limited to a specific age: Cassandra is just as capable as any adult for the task.

And Yelena does take a measure of comfort in the shadow of the younger spy being there. Even only at the edges of the gathering, mostly noticed by Yelena and no one else. No one is here for the kind of social mingling that a party might create, after all.

"Thank you," she whispers, voice wavering in a way that betrays any attempt at keeping herself together in that moment, as she watches the petals float gently on the water.
