How would the WT react?
Remember that the WT is always right, even when it's wrong, and that everything is proof that it's God's organization.
Hadn't Russell or Rutherford (I forget which) once taught that the moon was inhabited?
The WT will say that this proves they were on the right track all along and that their teaching just needed the refinement of new light (it was Vulcan, not the moon).
Oh, and by the way, Armageddon is just around the corner...
