I totally believe Nabu is back because when I researched the winx club season 5 episodes, I saw the title "Nabu's return" at the episode 15. And Aisha can't be the only one who had lost her boyfriend. Maybe the winx club creator don't want all the children to be sad because Nabu is gone. But it doesn't mean he's really dead.
