My mother can't help but busy herself when I'm over, and when I think about it it's always been this way. My grandmother (her mother) had to be begged to sit for holiday meals. And so it may be with me.
Again, Eve is assuming her Mom is already halfway to this conversation, when she has almost no context at all. She now knows her mother gets a lot of information from Hanna's mom, but that doesn't tell her what her mother is actually hearing, and even now that's a hard and maddening thing to discern. The truth is Eve's mother "only" cares about her daughter's health and material wellbeing, things that Eve herself neglects over the emotional journey she's on.
