AND SAKURA IS WORRIED
Because of course Sakura is worried
She’s put all her points into Empathy and she Knows when something is up.
So she looks back twice when leaving with Fai, and it’s not until Fai assures her that Syaoran is safe that she finally allows herself to be drawn away.
And again, Fai is actually very good with words when he wants to be, because he doesn’t lie here. A lie wouldn’t work. If he said everything was alright when it so obviously wasn’t Sakura might kick him out the window. (Which, ok, might be unlikely, but I would still love to see it)
Instead he points out that Syaoran is safe, and that’s the part that she connects with. Because, in all their travels, Syaoran is so rarely safe, and even less so when he hides his wounds and never tells her when he’s hurt. So here he is, both talking about his problems with someone AND safe to boot, so Sakura is, for once, satisfied.
And it probably helps that Mokona still has that hat.
