Well. He thinks that this wasn't quite what he expected death to be, and that the Hinterlanders were, unsurprisingly, absolutely correct about the Nikara understanding nothing. He thinks that if he's not careful, he's going to get caught up in a spiral of guilt, picking apart every single time and place where he could've tried harder to redirect Rin's destructive fury. He thinks that perhaps the destruction of his world was decided long before he, Daji, and Riga clawed their way into the Pantheon, and if he can come to that conclusion from the barest scraps of memories he's unwillingly regained, what will he think when he has the rest? Most of all, he thinks that he's not sure what he'll do if he completely cut off from the Pantheon in this place, beyond the roadblocks he already had back in Nikan.
