Well, it all depends on the Xeno, if we are talking Canon, we would be fucked up by the things it would say.
Then lets say we could communicate with a character one of us has created. Here is my assessment.
Bloo: Freaked out and covering Genitalia
War: Sorta indifferent, haven't really seen much about his character.
Dronehive: Running and freaked out.
Blizzard: About the same as War, again haven't really gotten a feel for them.
Badapple: Just scared kinda.
Firehunter: Running out of pure terror
Lioness: RUnning and trying not to be eaten.
GameFreak: Running, freaked the fuck out of what the two minds think together.
