[Seonho leans in to look more closely at the seal, but he doesn't have nearly enough experience to make any educated guesses about it, besides the conclusion Zhongli has already come to. He does look worried though, at the idea that their summoner has power to suppress Zhongi, of all people, and that Zhongli has to adapt himself to this restriction. So even if Zhongli isn't exposed to whatever danger Celestia might inflict, he has to contend with the dangers he wouldn't have had to deal with if he had his full power...

Seonho sits back, brows still furrowed with concern. but he manages to make his voice sound light.]

Any assistance you decide to provide is invaluable, Zhongli. Just this conversation alone has told me more than what I could have discovered on my own. ...You have my thanks.

[no matter if Zhongli decides to keep other things to himself -- Seonho knows that in some situations, more information is not necessarily a good thing. Also, since Zhongli has been so transparent with him...]

...I would also like to be honest with you. Shortly after I arrived here, I met someone from my world. [he pauses. it's hard to speak of Hwi, after Seonho's trained himself so well not to back in South Sister.] He was not in South Sister with the rest of us, and he was not aware of my disappearance from our world when I asked. ...His name is Hwi. If you ever require assistance, then he would be happy to help. He's a skilled hunter and smith, and his capacity for kindness is far greater than mine.

[no matter if Hwi's mostly focused on getting to return home, Seonho knows that he's the last person to refuse anyone else in need of his help.]
