“They are younger versions of us. Lan Wangji is ten years my junior. Wei Wuxian even younger. I have met both, briefly.” Nevermind that hot and heavy make-out session with the younger Wei Wuxian when he was under the control of another. They’ve spoken since, but Wangji keeps to himself. Not his Wei Wuxian, not his business. There is much going on of which he’s unaware, but the juniors seem to have a finger on the pulse of goings-on among them.
