Keira is about to make a snide comment, probably something to do with the fact that he's more snake than dragon and might be better off slithering home, or something along those lines, when Zara cuts in. It is clear that the girl is trying to stop a fight before it starts, rightfully so given that Keira and Draven are both capable of being some of the more dangerous members of the student body if provoked, but Keira's eyebrows remain up. She looks at Draven with the sort of curious displeasure that one might use while observing a stranger vomit, or a grotesque creature previously unseen. Her gaze adds a very slight smirk, or perhaps the beginnings of a grin, to its arsenal, even as Zara decides to try and placate Draven over Zara. Taunton might interpret it one way, but to Keira it is a sign that Zara believes Keira less of an egomaniac. Her temper is no less dangerous for this, of course, but it luckily is able to simmer away. Were it not for Zara, she might have been prompted to challenge him to a duel already. Plenty of people, muggleborns and halfbloods alike, might have rallied behind her for this.
Keira's smile grows once more, as she seems almost ready to chuckle at Zara's little act of a damsel, knowing the girl to be far from it indeed, "What's Taunton going to do --make eyes at the dragons until they go away? Please." Keira responds dismissively. The arrogant side of her does not view him as a significant threat, not when parted from his wealth and influence. Behind the money is an average wizard, as far as she's concerned, and Keira decides to let it slide for the first day of school. She supposes the Head Girl can't be starting fights on the very first day, after all.
Not the sort to be concerned with appearances, she is less than impressed with Draven's comment about telling them where they lie on the 'hottie list' or whatever nonsense he's spouting. Were they friends, she might have found the comment amusing. As it is Draven, she merely finds it boring.
"If it were, they wouldn't have chosen me," she responds breezily, before looking at Zara. It is a good thing that her rivalry with the girl had evolved into a friendship, or else these two would be absolutely sickening to Keira. "I hope you'll keep your wand out --he's likely about as useful as a porcelain flower vase. See you at dueling club, yeah? I've got to get to Charms."
She glances once more at Draven, giving him a critical sort of once over before laughing lightly to herself, her thoughts going unstated but the fact that they only dismiss him further clear, before departing from the duo to head off to Advanced Charms.
