Draco might have wanted to be present at the reception even less than she did. She thought it was a bit cruel that he was expected to attend the celebration of the marriage that was designed to essentially replace his best friend, especially with his suspicions that Theodore was responsible for the explosion. While she pretended to speak with Lucius, Antonin engaged Draco in a conversation. Though she'd had plenty of experience watching her husband converse politely with one of her lovers, somehow it was different and more disconcerting with Draco. Maybe because she knew about his connection to the Resistance. There was a time in the not-so-distant past that she would've gladly turned him in for treasonous acts.
