Theo skips sleep pretty often, so when he does actually sleep he tends to sleep for a while. Kaede will probably wake up before he does.
He pauses. "That off-hand thing he said about me being fine means I'm his guardian?"
"I'm sure he – wait, no, she? – I'm sure they did, but it was very brief and people seemed to consider it a very important thing and I wasn't expecting it to be something I could have missed."
"Yes? But in a more general 'this is a person and oh my fuck Sin and he seems like he's actually doing something about it and also was my literal summoner' kind of way! Does this have repercussions. Am I disallowed places because I'm magically– their guardian?"
"You followed him and protected him on the Mi'ihen Highroad. You helped her and sought her out on the Mushroom Rock Road. You are planning on returning to him to tell him of your findings." He shakes his head. "You are his guardian. You can go wherever he goes."
"… About the fact that I saw where Tidus is presumably from and nobody remembered him nor remembered the recent attack nor anything, or about how Jecht is inside Sin and a guardian will get screwed over to become the next controller, or what. And why."
"… Because Zanarkand will somehow be impacted by Sin disappearing?" asks Theo. "Does this happen to, by any chance, have anything to do with them all being magic because seriously that would fucking suck."
"… I thought they were all statues and only summoners could interact with them in the cloister things. Or, like, Jecht, but I don't think most people know about fayth-turned-Sin-controller."
"The statues are connected to us, and they're where we sleep. We're not limited to them, and Zanarkand has enough pyreflies other people can see us." And indeed there are as many pyreflies flying around the skies and floating from the ground as there were inside Sin.
"Well, that's… somewhat convenient, especially seeing as how you're sort of immortal?"
Sigh.
Theo decides to be potentially rude and test that the fayth is indeed magical, and so he tries to change a patch of the hood blue.
The fayth is very much magical.
"You should return to your summoner, and guide him so he can end Sin."
"i agree," responds Theo. "I will perhaps see you and these ghostly apparitions shortly."
Unless there's a response, he'll fly off.
