Decision

Rouge and Oumu started to walk towards the deeper parts of the Patriarch Room.

This is because Rouge led Oumu in this way, and this is because this is where their destination is set.

It was weird for Oumu since Rouge said that he left it to someone who he trusts, and if Rouge is leading Oumu to this person, then...that would mean that this person is inside the deeper parts of the Patriarch Room.

And that was weird. The only person who should be allowed to the deeper parts of the Patriarch Room is the Patriarch himself.

Of course, since Rouge could be considered to be the Patriarch right now, he is allowed in here, but...even if Rouge trusts this person so much that he would let him hold the official document signed by the Patriarch, which could be considered to be Rouge's lifeline right now, this person should still not be allowed to enter in the deeper parts of the Patriarch Room.
