Actually wild. Though not exactly. Their souls are definitely connected though, and they can communicate between time-lines. And even summon each other as ghosts. However, since Cloud is still crazy at this point, it's making his dementia much worse than it was originally. His hallucinations are now intermixed with actual visions of other timelines. Big upgrade for Zack too. Since now he can one vs one Sephiroth. When before he was outmatched, and he can even fight Sephiroth with the black materia or as Bizarro-Sephiroth.
