"Is the Holy Church about to attack us? Or they don't know about this yet?" the clone asked Eren, walking closer to the window to peek outside.
If the Holy Priestess was kidnapped and taken hostage, it was only a matter of time before the Cardinals were going to surround this place.
"I don't think you will have to worry about the Cardinals anymore. The Holy Church is..." Eren started explaining, only to stop in the middle.
He realized that explaining it was going to take a long time. Instead of explaining everything, he simply shared the memories of the entire incident with his clone.
Although his clone was useless in an actual battle, he was still useful as an administrator. Eren didn't want to deal with the massive vacuum created with the destruction of the Holy Church.
The Royal Family had to take the lead and stabilize the situation. As this was a time consuming process, Eren left it for his clone to deal with.
