I mean, I certainly don't want her to get killed cause she's one of my favorite characters, but given how the house of black and white can infiltrate any situation, I really really really feel like it was very unlikely that she just left and there was only one attempt on her life by the waif.

I need to see some sort of bounty on her life by the faceless men, I need to see her racing to stay ahead of them, maybe Jaqen teaming up with her to save her life.

To me it's yet another loose end that the writers did a poor job of covering.
