Tony Stark. He's one of the leading engineer scientists from his world, it looks like. Smart guy. [ The way he said it meant that Tony still didn't replace his crew. The crew he hadn't even started the One Year Mission with yet. Stupid time. ]
Looks like it. [ Kirk was in the linguistics club in the Academy! He knew how it worked. That didn't mean he had the natural talent Uhura did. ] I can understand someone perfectly from Medieval Europe - Queen Elizabeth I, by the way - but sometimes things get weird with the natives.
