That’s one way to not get invited again to The Ellen Show.

I understand they have English speakers as some others have mentioned, but other than introducing the members and music there wasn't anything else to talk about on Ellen. Not to mention most "non-generic" questions they can't even answer truthfully do to agency rules. They got the "girlfriend?" question, and we all know they will never answer that with the truth. BTS basically had the same interview when they first appeared on Ellen, so it was honestly as standard interview. The language barrier makes things awkward from the start even with English speakers, because it limits who can thoroughly answer questions. Also, Korean variety shows will feature that one artist or group for a whole show, and American talk shows don't work that way.
