What she's learned so far about this city is...well, it does help somewhat in alleviating her disorientation, however incomplete it is. But in simple terms, it isn't enough for her. There are four wards, others have also been called here (though, curiously, not all Servants and not even all human or faerie), the hole in the middle of the city leads to some void not unlike the pit that the Camelot of her homeland encircled--but who has called them here? Why have they been called? Does this place reside within Proper Human History, or in some other sort of offshoot?
These...are questions she likely won't be able to answer today, nor without considerable time spent investigating, two realities that don't sit well with her. But some of the other curiosities she has, such as what the other wards are really like, are ones that she can satisfy at any time.
And so, she has decided there is no better time than the present. She's decided this, at least, until she actually opens the door and steps outside to see another familiar face, walking down the road.
"...Melusine." The Tam Lin who took on Lancelot's name is...a complicated subject for her. It's not that complicated, actually--Barghest knows for certain that she doesn't like Melusine all that much. It's more of a question of the reasoning; they don't actually disagree on much of substance, it's just...something about her personality irks her, for some reason. And as certain as she is about the feeling, she's less concrete about exactly what that reason is. "They're keeping the three of us in one area, I suppose. Do you think that's by accident, or on purpose?"
