"Get out," Ren said to Hannibal as he opened the cell door. Ren was originally going to kill Hannibal, maybe even do something worse; however, once he heard what Hannibal had to say. He no longer felt like disciplining Hannibal or taking any kind of revenge. Hannibal was far too gone, far too delusional, just like how Yuna was.
Ren could see that no matter what he said to Hannibal, nothing would get through to him. Taking any kind of revenge or punishing Hannibal was no longer part of the question since Ren knew that this was something Hannibal was after. It was like he wanted to be killed, so Ren no longer felt the urge to do anything.
