As the phantom was approaching Calais, he was abducted from his home by Anglican agents and brought to the container yard for interrogation by Agnese Sanctis, along with the other magicians who had used the shipping container in which the summoning ceremony was performed. He was initially deviant towards his captors while his head was in a sack and his wrists were bound, but Isabella Theism's words on what his bindings were made out of caused him to vomit. Answering truthfully about what they were doing, none of them knew the required exorcism procedure as they were not aware of being part of the summoning ceremony to begin with.
