Arret, John, Tina and Bobby see Zipaxz and Gellax in deep conversation, not noticing the first four mentioned at all. They walk over and ask what's happening. Gellax responds by saying that they're looking for someone, and inquires about their progress. The response is not known, due to the fact that Elects attack. Zipaxz muttered "I thought that these guys were long gone!" Gellax shrugged and open up a Black Corridor, which he and Zipaxz go through when they destroy all of the Elects. Arret, John, Tina and Bobby wonder about what just happened.
Vanitas obviously has the upper hand.
