I believe they both need time to grow, before they can face each other again. What good would it do to meet if they were still unable to see eye to eye, unable to understand each other’s thoughts and motivations, unable to accept each other’s good and evil? This is why I feel a reunion would be too uninteresting if they were the same people as they had been when they separated. Nezumi, though admitting to being afraid of losing Shion and comfortable with opening his heart to him, was scared to see Shion’s true nature, to find that he was capable of cruelty after all. Shion, though thoroughly devoting himself to Nezumi, longing to be by his side always, could not, or was afraid to accept, Nezumi’s dark side. I believe it was this narrow point of view that led them both to fail to comprehend each other, when they should be able to. Shion had not had the time to grow into his own person, to figure out his true nature. Shion, likewise, had his life practically shaped by the time he spent with Nezumi Nezumi was one of those who moulded him, together with his mother. Nezumi had plenty of experience surviving, but he had not seen the world and himself outside of No. Even though they compliment each other well and made an excellent team, both Nezumi and Shion did not have much time to grow as individuals. But at the same time, it also makes sense. And yet, it seems they cannot comprehend each other. The way they are, one would expect them to be more similar than they thought: they are both “good” and “evil”, and nether at the same time, as Rou pointed out. He thinks they each have a role to play, and Shion’s role is to never dirty his own hands. Nezumi didn’t want to accept this he didn’t want to see the cruel side of Shion, just as Shion refused to accept the cruel side of Nezumi. He could be all of these things at the same time. Likewise, Nezumi didn’t understand Shion’s split personality: he could be kind one moment, and ruthless the next he would be gentle to every living being, but ready to destroy anyone who tried to harm Nezumi in any way. He could be kind to Shion one moment, doing everything to save his life, and ready to slice a throat with his knife the next.

To Shion, Nezumi was a deep, dark forest, completely unfathomable.

He didn’t understand that Nezumi’s approach was helpful in softening Fura to the point where he was ready to listen and start a conversation, ie. He didn’t want to see a “false image” of Nezumi, or something that was not his idealized image of him. Shion couldn’t understand why Nezumi chose to torture and interrogate Fura to extract information from him, refusing to accept that Nezumi had a cruel side as well as a good side. As a result, they both have idealized images of each other and can’t stand to see that image change under any circumstances. They lived together for almost 6 months, practically together 24/7, see the same things, get involved in the same fights, and yet were not able to see eye to eye on most things. It’s not so much that they don’t agree with each other, it’s that they can’t understand each other in the first place. Again and again, Nezumi and Shion have been puzzled by each other’s way of handling things. To understand someone means you must see as they see, think as they think, and adopt the same mindset. Even though they are devoted to each other, and willing to die for each other, they haven’t once seen eye to eye with each other (at least from what I gather reading the translation of the novels). It was suggested again and again that Nezumi and Shion are unable to understand each other.
