Much said 'yes' because he couldn't say: I'm sorry, I can see right through your robe. And also, this apartment, excuse me, but fuck off.
In terms of excessive, ostentatious wealth, this place was as terrible as Peitho and Hermes had been, but Much was really, really putting a concentrated effort into not showing what he thought. It hadn't gone great last time he'd tried to ask a goddess exactly how she justified this kind of opulence while people were starving.
He'd watched Marcie as she stepped in, she obviously didn't hate the place, so Much tried to push his outlaw-conscience down. She didn't need another complicating factor in her life right now, he could save up his opinions and tell the others later.
He should really tell the others he and Marcie were okay, he thought, but Aphrodite was addressing him directly and also she was basically naked.
So he said 'yes' and gave her a wide smile in return, eyes carefully above neck height. This wasn't too difficult, she did have an exceptionally beautiful face, and she seemed kind, and despite the wealth he wanted to like her.
