Character mistake: Scarlett says that since McCullen is from Scotland, he speaks Celtic. Celtic is a group of languages, not a language unto itself (something a genius like Scarlett would most likely know); it would be like saying someone speaks Semitic or Germanic. McCullen would probably speak Scots or Scottish Gaelic, the official languages used in Scotland.

Suggested correction: Scarlett certainly took this into account when she suggested the words for Ripcord to speak. Scottish Gaelic is a Celtic language so Scarlett was still correct, she was just simplifying for expediency.

No she wasn't correct. There is no such language as "celtic."
