If they keep sticking to the manga and the two chapters per episode like they did so far, it'll be in three weeks.

Elfman will probably serve as cliff-hanger next week, then it'll all be about the other two locations until it finally returns to the guild-hall in episode 241, where the scene you talked about will happen.
