Well to me the decision seems pretty obvious. Kick him out... and that's exactly what Ayumu is doing. Great minds? nah... just good old freaking common sense. Kane thought to himself listening to the two Sennin talk to each other and then Ayumu talking to the memory loss Uchiha. He wasn't stable, he didn't prove he wasn't a threat and his eyes were more advanced than ordinary Uchiha, or as ordinary as they come anyway. Kane continued to stay quiet and in the shadows in the back of the room. Kahako got the easy break and was able to leave. Kane was stuck here to deal with this issue... if it were to come to one anyway. All in all the last few minutes were boring with all the waiting for them to be done interrogating the guy. If it had been Kane's decision, he would have left him outside the gate to die after attacking him. He wouldn't have wasted Medical treatment or food or water on the man. He made his bed, he could have laid down right there outside the gates in it. But alas he called the ANBU Sennin here on his own accord. It was his fault in the long run. He stood there waiting to make sure there wouldn't be any fighting. No blood shed was needed today.
