I've wondered the same... especially given how they were little inclined to attack anyone, before. [Of course, how much of that was Merlin's influence and how much not-- it's hard to tell for sure.]
I must say I hope they've stayed... they're very fascinating. I'm sure there would be much more to note about them. [And she wants nothing if not complete notes on them; complete notes that she could bring back home with her, no less. Because things like dragons that don't exist... what if she could somehow make it happen, through genetic experiments? How wonderful would it be, to create a new life-form, or even the basis for it? ... and how precious, too.]
Of course, if they're set on hostility... well, we'll see, I suppose. [She doesn't seem the least surprised about Sebastian's relative unconcern regarding the monsters-- and really, she doesn't herself seem too worried, either. There's her gun, strapped under her coat, and she trusts it will get her far enough.]
