"Better poetry than visual arts appreciation." Matt laughed. If he did it first, it tended to put people at ease. And if he was honest with himself, he wanted Wanda to be at ease. It seemed like a state of being she wasn't in very often.
Being the observant person he was, he couldn't fail to miss her deft evasion. She'd make a frustrating client, that's for sure. There was just a touch of Karen in her, enough at least to make his protective instincts kick in. Just like her, Wanda didn't really need protecting, but that didn't keep Matt from wanting to.
So, he didn't call her out for not answering, one—because it was rude, two—because he was too busy being charmed. "It's a deal, Ms. Maximoff. It'll be nice to have someone around who won't let me be a fashion disaster."
