I have no doubt that the Crystals were there. But I'm not sure the interpretation that they went there to say goodbye is correct. I think they went because they didn't quite believe what Romy told them and wanted the see what had happened and if they could help out in some way. Maybe they did see the uncovered bodies but I really hope they didn't. I mean, how do you recover from seeing something like that?!It would be unusual. They have pretty good sources, although they have sometimes been wrong.
