It's about at that point that he spots a rather familiar face. His eyes widen, something like surprise, followed by relief, warming in his chest. To see anyone at all that's familiar, especially in this distressing situation, has him reacting almost excitedly, though perhaps with a bit of an edge of desperation.

"Ah--Hanguang Jun! Hanguang Jun!" He lifts an arm, waving in a way that's almost desperate as he makes his way over to him, pushing past people in the crowd.

"Hanguang Jun, I--" It's about then that he looks up at his face and abruptly remembers how consistantly nervous Lan Wangji has always made him feel, and he falters, starting to lower his hand. "....ah. That is...you are also here." He might have mumbled that last bit, gaze skittering away from Lan Wangji's face.
