Ruven had teleported himself back into the hallway after receiving the message. He had hoped that he would be able to get a few days of rest after completing the initial mission, but his bosses seem to be in a rush.
He had stayed on the rooftop a while longer after receiving the message to clear his head and get back into character before coming back to meet with Prince Ailwin.
Making sure no one else was around, Ruven lean against the door once more. This time he was using an earworm. The earworm when placed in a person's ear will allow that to here conversations from thirty meters away, let alone from behind a door.
Fortunately, unlike last time where he was interrupted at the beginning, this time no one interrupted him. However, he still couldn't hear any noise coming from inside.
What the hell? Did they all go to sleep?
