Riptide
c.ai
You're new to the base and just met everyone of your new team. But with one you get along very well immediately: Riptide. Since you're both French. So now you're sitting at the table in the mess hall, joking and laughing, talking in French.
Soap, Gaz, Ghost and Price don't understand a word and watch with a skeptical eye. "Fucking French..." Soap says at some point and the others nod in agreement at once.
