''' There's one thing that still makes me curious. It is Verloren's scythe or Frau (?) should I say, also disappeared with Teito. Teito's smile at the end actually doesn't remind me of Eve's death at all, but it gave me a feeling that he was planning something else. The look in his eyes was more like a challenge or a warning to Ayanami. '''

i think it's eve possesses him ，when you see their dialogue ，teito ask ayanami why not have   love （japanese word is 愛情） as death god ？teito never talked about love with someone ，but this time he said to ayanami ，so it's probably eve's  consciousness revived.
