It might have just been the mask, but Tony didn't look particularly surprised. He settled on the edge of the chaise next to her, leaning with one hand pressed into the cushion on her other side, leaning his head on his shoulder. He hadn't been in contact with the team lead by Reed and Sinister since he had entered New Orleans, but Sinister had turned their focus that direction before Tony had left them-- he hated that he had wished Sinister was wrong, but his lips pursed with annoyance.
'Williams', though, that was more interesting information. Tony worked the tightness from his jaw to touch his tongue to his lip while he considered that name; systematically evaluating the likelihood of anyone named anything like 'Williams' that Tony had the phone number for being involved. With that system running in the background, he slowly lifted the hand in his lap to touch the feathers of Wanda's mask and asked, "Where'd you hear that? Maybe we should find out who they're hanging out with." It was offhand, like he wasn't really paying attention to the words, and he smiled at her when his hand dropped.
