It's crazy on their first meeting just how closely Rocky was studying Grace;
-he noticed that Grace looked through the window, and realised he could only see through certain types of xenonite, and so changed the whole wall to that type.
-He realised that Grace wore a helmet. Would we work out if Rocky was in an exosuit, or just assume that was his anatomy?
-He was able to discover that Grace breathed oxygen (genuinely have no idea how).
