A few hours before Guy rescued Al from getting dissolved inside his Student's core. A long-awaited confrontation took place inside the RoK.
"I need to hear the truth, Mast," Guy declared. After entering the RoK, he now faced Mast's avatar, which also happened to resemble Guy's form from his past life. "The whole truth, about my death."
(What's there to learn? I've told you everything,) Mast shrugged.
"I don't believe that you have," Guy rebutted with a frown. "You have been lying to me. I want to hear the unadulterated facts."
Mast tilted his head. He then waved his hand, causing a seat to materialise behind him. He lowered himself into the chair and rested his chin on his closed fist, which was supported by the table at the centre of the RoK.
(Let's say that I have been deceptive with you, what reason do I have to reveal the truth to you?) He asked, breaking the charged pause lingering in the space.
