How much of NRG speaks Korean?

I know GBM and Impact obviously do as former KR pros, and I think Konkwon does bc his family of origin is from KR. I know Pobelter who Altec played w/ speaks KR because of his family of origin, but for some reason I feel like I heard something about Altec being able to speak Korean as well when that roster was being talked about. Does anyone know if that's true, or if Moon speaks any Korean? Even if only Alec does this might be the most a team has been comfortable communicating in the native language of their imported star players, so there's the potential the line up may work better than how some team moves have turned out. However, jungle is a big role in terms of team communication (especially early on) and I wonder if Moon is the only player who doesn't speak the primary language of his solo lanes how much that will hurt synergy?

Either way I'm looking forward to the line up and hope it works out (I like impact and altec as players so I hope they have a good run w/ the new team).
