He would listen to the report fully, remaining silent throughout all of it. He was never a fan of those who interrupted in the middle of someone, at least while working under this mask. Under this mask, he found the best course of action was to let people talk as much as they want, as long as they want. This gives them a chance to state enough information to start to piece together a better picture or enough rope to hang themselves.
"Joker..."
There had been a lot of questionable things, and the story within his report seemed almost fantastical. It would be incredibly easy to doubt this person and call to question everything they've said since being back in the village, to question their actual time in Kumo and to attempt to pull out any information he thought might have been hidden. And yet...
"...welcome back home. I hope this report means you were able to secure the Fox contract, especially if it will be of a great aid to this village."
He would then do something he rarely did, especially within this mask. He would place his hand upon the shoulder of Joker. There would be no ability to convey real context or emotions, because of his mask and voice altering, but he did not care.
"I am concerned about whatever may have happened to you to cause you to lose track of such a large amount of time. Please, head to the Omni Prime to get an evaluation completed before you begin your duties as an ANBU."
Joker was one of the first new members he inducted into the branch following his full transition into control with Reaper. Due to that, he would do something that he wouldn't normally do in these types of situations, especially when he had doubts; he would trust him. Hopefully, all was well.
"That is all, thank you for your report."
And with that, Tenken would turn around and begin to fade back into the shadows.
[Tenken has left the thread]
NPC Usagi - Still in Comms Room
Her eyes would turn to the monitor picking up the visage of Ruin. His voice would come over the intercom system as he was requesting to be let in. She would notice that behind the door would be Tenken and Joker still having their conversation.
"One moment... Ruin..."
She hated talking, literally the worst thing. While she hated communication, well more so the act of her communicating, she was not oblivious to listening to what and how people say things. It was a skill she had learned a long time ago, allow people to tell you everything you need to know. It was a similar approach to Tenken, but with much less follow up conversation. She was not skilled in his art of continuing to poke and prod at something, she was much more of a listen intensely and then go punch the whoever or whatever it was once it went quiet.
"Tenken is finishing... something..."
Hopefully, that would be enough to calm the apparently frustrated Ruin. There was a chance it would not work, there was a chance it would quickly escalate with him following up to his threat of 'opening' the door himself. His reports on previous missions seemed to have instances of rather high scale damage, there was a high degree of probability he was capable of powering past their door. It would not have been the challenge of another DOOR, but it would also not be a slouch of a door.
Tenken would then leave. The door would begin to whirl and snap, slowly opening once more.
"You are clear... Ruin..."
There was no reason in her mind to suspect something would happen from this looming encounter, so her eyes would not remained affixed to it. Instead, she would continue her vigiliance to watch all the different monitors. It was the part of the job she did enjoy.
