Teito was reincarnated (when you collect all 7 tickets and enter that purification land you get a wish granted) and Frau became the new Verlorean (which I cannot spell) but still spends time with the ex-ghosts and Teito. (because verlorean absorbed all his fragments so they were all combined again)

And it's only little Teito who can see Frau/Zehel.
Noboby else can see him.
