RahXephon - Season 1 Episode 17 Return to the Labyrinth

Ayato and Quon are headed back to Tokyo Jupiter. Elvy is ordered to go out and bring them back, using the Vermillion, at any cost. Even if Ayato comes back peacefully, Iishiki plans to charge him for treason. Haruka asks to go with Elvy secretly, and she lets her. Ayato is almost to Tokyo Jupiter when Elvy catches up, and the two are about to fight when a Dolem appears to help Ayato. It distracts Elvy long enough for him to get through, then goes through too. Elvy also goes in after them. Ayato awakes in the hospital. His mom comes to get him and Quon stays there. On the way home, Ayato sees his friends and talks to them. Asahina freaks out, saying something's wrong and she's forgetting things. Mamoru tells her she's being paranoid. When Ayato gets home, he checks his blood, which is red. His mother shows him hers, which is blue. He starts to scream, and Quon wakes up.
