After a moment, Chastity finally took a sip of her drink. She got a bit of fudge as well, and as she chewed it, she briefly closed her eyes. For a second she was just a bit overwhelmed by the memories that came along with that drink. She had her own reasons for not wanted to be reminded of her mother; hatred and anger being the most prominent emotions. Thoughts of her brother were less about anger and more about... sadness. And regret.
At Patience's words, Chas glanced over at her for a moment. If he had lived... well, it might have been the five of them here. Their parents would, in all likelihood, still be alive. But Patience, perhaps, didn't know that. So instead, she murmured, "Yes... He was too young for me to really get a feel... but I always thought that even at that age, he had a bit of Ravenclaw in him. All that curiosity."
