"The minute he saw he, he tried to kill me! That's what happened!" Of course Xue Yang fought back. What choice did he have? And he wasn't going to just let Song Lan come in and spoil what he had.

"He was going to tell you my identity..the minute he saw me by your side he was angry. So I did the only thing I could...I took his tongue so he couldn't tell you."

Xue Yang isn't afraid to tell the truth but doing so brings that same psychopathic smirk to his lips. His voice almost laughing the way it did when he described things to Xingchen on that fateful day. he can't help it. When he gets worked up, there is nothing he can do to keep his voice calm.
