The Untamed ep 9
The first time around I kept forgetting that Jiang Cheng is the youngest, but his sneaking off after Wei Ying follows Lan Zhan in search for the Yin Iron makes so much more sense in light of this.
Also, Wen Qing was very close to open rebellion, wasn't she? <3
And even at 16, Lan Zhan was already incredibly powerful, stopping the zombies. (And then just walking off, bc Wei Ying had been paying too much attention to other people. Jealous baby! *g*)
