[ He's only fifteen and he has been through so, so much. Nanami's eyes close at the admission that Gojo is dead, that he's gone, and that he's going to come back and be in the same situation Nanami is in. He doesn't know what they're going to do, when there's just so much left unattended to. Weren't they supposed to be the adults?

But then there's more there. A binding vow? Sukuna took over Megumi as his vessel? The pieces fall into place a little more easily then. Sukuna's power combined with the deep understanding he likely has of Megumi's technique, more than Megumi does most likely. That must have been what killed Gojo.

The lack of eye scars too. Megumi arriving at the hotel from a time earlier than Yuji, probably because the hotel knew he couldn't arrive with Sukuna inhabiting his body. It all makes sense now and the tragedy of it is so obvious. He feels so, so bad for Yuji. That much to carry on such a young man's shoulders. ]

It's not your fault. I know in this moment it feels like every one of your decisions have led up to this series of events, that if you did anything differently things might have ended up differently as well. But that is not true.

I'm not trying to say that this was all predetermined or fate or anything like that. I just mean that the blame for this is not on your shoulders. Sukuna was a threat long before you joined our world and until he is gone, he will continue to be a threat. The curse users were also working together to bind Gojo before you arrived as well. Their attack on us was inevitable.

So, listen to me, while this is a tragedy: it is not your fault. If anything, it is our fault for dragging you into our world when you are an innocent.
