It's only when Tifa insists once again that she's happy for him that Cloud thinks something seems a little off. He might have mentioned it, except she immediately leaves for the restroom, and she's...in there a while. Was it something he said? Is she mad after all and just doesn't want him to know? She can't possibly still distrust Aerith, right? Or...maybe she was lying about not remembering Zack, and has beef with him for some reason?

By the time she returns to the table, Cloud looks concerned. "Hang on, everything okay?"
