Yuan's heart just breaks for him as he explains the situation and he reaches out to take Jin Ling's hand. It makes him feel even more overwhelmed that Jin Ling has chosen to trust him, chosen to accept the truth of his identity when he could have so, so easily just pushed him away and nobody would have blamed him even without knowing all of this.

"I know you can't trust Xiaowen." he says finally - he has to, he can't wait a single second longer and risk anything more happening, he just can't. Jin Ling needs to know the truth "I haven't... I haven't had the chance to talk to you about this, and I'm sorry, I just... I didn't know the situation was so awful."

He takes a breath, considering for a moment how to phrase the next part without giving anything away, but so that Jin Ling understood. Eventually he decides to be vague, he can clarify if Jin Ling needs him to, but he thinks he'll get it.

"I've met him before. He bragged about the ways he undermined his boss. It wasn't until I saw him yesterday that I realised he meant you."
