I woke up this morning and went, omg, it's not just that Shen Wei maps to Li Qian! Zhao Yunlan maps to Li Yufen, too! Sucked into a Hallow, and now he doesn't remember anything, just wandering around, grinning like a baby (and eating a lollipop!). And eventually his spirit will come out of the Hallows to protect [Shen Wei by proxy]!!! (Honestly, I can't remember if I've noticed that before, but it just hit me.)
