Morag was back to wondering what Percy and Antonin saw in the girl because she, personally, was having a hard time not snorting or rolling her eyes at the vapid things coming out of her mouth. And if that wasn't enough, she was openly flirting with Antonin when she had no intention of following through on anything! And she thought it was a good thing!!!
She thought Draco's statement might have been intended as a compliment, but he was a Slytherin so she wouldn't put it past him to have been teasing her, thinking she would take it more favorably than he'd meant it.
Then she wondered if she was thinking too hard.
However, she turned to Antonin and asked sweetly, 'What do you think, darling?' She wondered if he'd recognize the landmine before he triggered it.
