It seems like a risky deal. You don't know this Marina. She might be similar but it's an awful lot of uncertainty and pledging protection without knowing what she might be up to? That's risky. I don't think anyone in our group is going to be an issue, and probably not even the whole community, but a word as bond with a person you don't really know is a gamble.
[...] I still think a word as bond is risky even if you want to protect her.
