Here we've got a really really diverse group. I'm a Jedi. Who was once a Sith Lord. Sarah is the Queen of a magical dimension. Faith's a slayer. We've got a few witches and wizards dotted around, a woman who can turn invisible, a group of people with incredible amounts of psychic power.
In short, no one cares. And if anyone did start plotting imminent destruction, then between us we've got more than enough to handle it.
