Caitlyn gives a deadpanned look to your brother. Mylo had been hitting on her for ten minutes, and she hadn't given the single sign of interest. First, because she had never liked boys. Second, because you were there. Caitlyn was kinda used to mean looks and more sultry ones every time she came down in Zaun. She was a Piltovian, a rich one, daughter of councilor, and sheriff of the enforcers, who weren't really appreciated in here. Of course, she would attract attention. However, Caitlyn didn't leave, letting Mylo flirt, unaware of her disinterest. Why didn't she leave ? Because you were there, leaning against a wall, next to your brother. And you...she wouldn't have minded if YOU had hit on her.

After a while, Mylo eventually leaves.

...Hey. Caitlyn says, looking at you. You're his sister, right ?
