[If she hadn't somewhat wondered that's what he was working up to, Rin wouldn't believe him. It still gives her goosebumps... And she can only imagine what a blow this is to him.]

You did say you never saw him again... So you were right the first time, and he really was alive all these years.

[She ponders something for a moment, before deciding to approach and sit on the bed too. Not right next to him, but on one corner.]

No wonder you're so messed up. To find out that, and that he's the one that was threatening so many people, even turning against you. [Rin looks over at him.] If you need to take a few days for yourself to process this, no one will blame you. We can just tell anyone you don't want to get into the details with that you got a stomach bug.

[Because, uh. That certainly frames that secret in a new, horrifying light.]
