I can help with Spanish... You already know that ;p

I'm not anywhere close to being fluent and I speak the Mexican dialect, but I know enough to get by on.

French could be cool to learn, but I'm already worried that I'm forgetting my Spanish since I don't speak it nearly as much as I used to, so tacking that on would be hard.

I guess Tagalog would be the only other natural choice, given that Jay is Filipino and they use a lot of Spanish words or mash ups of Spanish words.
