She did not think this through. How does she respond to that? She has no fucking idea, and she's scared of doing it wrong because Diego is generally at his prickliest when he feels vulnerable.

Her first thought is, well shit, she has no clue who Eudora is. Did Diego lose someone in the last few days and Vanya didn't know? She has no idea if that speaks to Diego's awful communication skills or her being a terrible sister. Probably both. Her second thought is to wonder aloud if Mom has a soul and if they'll ever see her again. That thought depresses her and will probably set off Diego, so that's out too.

But it's monumental that Diego even answered her question. She can't just let his answer hang there because she's afraid of saying the wrong thing. She has to try.

"I'm sorry," she says. It's awkward, and she wants to stop with every fiber of her being, but she plows on. It's easier when she focuses on Diego's heartbeat, faster than before but not agitated. "I miss Mom too."

As far as she knows, Mom was killed by the assassins who were after Five. She died alone after her children squabbled over whether or not they should kill her themselves. Vanya has doubts over their mother's independent thought, but she still loves her and knows her to be the only real source of affection she had growing up. The only source of affection many of them had.

"Do you... want to tell me what Eudora was like?"
