I would love to see Childe go back to Liyue before joining the project stuzha stuff and when Zhongli sees the state he's in, he insists that Childe stays for a while and he does his best to take care of him. (Yes, I just want Childe to get a hug and someone to care) And Childe decides, although he thinks he's totally fine, no problem, this is the perfect opportunity to dodge Pantalone's yapping. Oh woe is he, no way to leave right now, it's just not possible
