[Qrow's revelation comes as a shock; she doesn't know a whole lot about Semblances or how they work, just that, as Ruby described, they are essentially a superpower. Superpowers should be advantageous, it feels particularly unfair that Qrow's is not.]

I'm sorry. I didn't know. That suddenly makes a lot more sense - I thought you were just mad because it was Ozpin. I didn't realize...

[She sighs. The context does certainly does help explain a lot more about why Qrow reacted so strongly, and was so slow to forgive her and she's well aware that there's some things she could clear up on her end too, given how little she was willing to communicate in the heat of the moment.]

There's probably a lot about vampires at home that I didn't explain well at the time because... well, I was upset too. It's, uh, not really like here. When someone gets turned into a vampire at home, they're gone - a demon sets up shop in their body, and it walks and talks like them, and it's got their memories, but it's - it's more like a really, really smart Grimm that can trick you into thinking it's still your friend, until it decides to kill you. That's what I worried had happened to Oz.
