Charlotte gave the blonde with the knife several seconds to react, but apparently she didn't actually plan on attacking Howl. As the brief but volatile stalemate seemed to clear up, tension left her as well and she stopped pointing her pistol at people. It remained in her hand, however. 

The notion of food didn't phase her. She had no plans to take the gas mask off, and obviously that made it impossible to eat. She had also never wasted a thought on the question if there would be other masks before, so her enthusiasm was limited - in fact, she thought it was a bit of a bummer to [i]not[/i] be unique and invincible, because Howl and herself were indicative enough that [i]all[/i] masks had some set of special abilities connected to them. Including megalomania, as Dite splendidly demonstrated.

"[i]And what is this[/i] facility [i]for? What are we to you, rats, guinea pigs?[/i]" Her muffled voice was accompanied by intent glares towards Howl.

She ignored the cheery round of handshakes and introductions, hardly interested in social networking with the people who potentially had the power to de-power her. And she was even less interested in running a maze for the grim reaper like some kind of rodent.
