[Was she afraid that Luz would stay away? No, Luz had understood what was happening at the time, and she'd not held it against Sharon. This new development was enough to knock Luz for a loop though, especially since she hadn't expected Rose to go anywhere. She'd been a mom to a lot of people, Luca included, but with Luz specifically she had seen her at a particularly vulnerable state, so she was thrown for a loop right now.

She WAS, however, going to be careful about what she said. She'd try to help Usagi when something like this had happened and so thoroughly messed up their relationship it had never recovered since, so she wanted to only stay as long as she was allowed, and would leave when asked].

I can leave, if you need me to. I know this is probably really hard for you. Rose...is a very special person, I wouldn't blame you if you wanted to be alone. I just had a feeling you might not, in a way.
