Remember, FT is already in some hot water when it comes down to the MC, and I even remember them saying that if they have one more major slip up they they would be disbanded. Imagine if the MC found out somehow that FT's first master has a connection with Zeref? They would use that as a means to turn them into a dark guild no questions asked.
