Definitely!! Rainer knows German very fluently because of his parents who traveled straight from Germany, Josue knows Spanish fluently (and ofc so does Jenny), Josiah speaks some Hindi, but barely. Thorn knows a lot of Swedish but can be thrown off a bit. Curly and Grant both know Irish fluently. Would also be mad like Sean that they don't pronounce Colm's name right. Jailbird knows German as well. And then I have an unnamed Welsh guy who speaks Welsh fluently too.

On a sidenote, Josue would try to insult Jenny in Spanish and then be shocked she's fluent in it, but he would have a hard time understanding her thick Chilean accent.
