But Emma also lied to him at the same time because she also had no other option..

Because when James answered her and asked her why did you faint after seeing that magician..so, did you already know him..??

James already knew the whole truth but he was looking forward to hearing from Emma's mouth but Emma lied to him without thinking anything and started saying that no, I did not know that magician , and I was just suddenly got sick...That's why I was fainted...

And saying this she averted her eyes from him..

James knew that Emma was lying to him but he did not say anything after hearing...
