I don't see how you got "你和犀利妹妹没有深仇大恨吧". He, a little too serious may be, was simply trying to point out with reasoning and facts that there might be a liar out there fooling the audience with bogus claims.
As long as I am a girl, I can lie here? Interesting. I can fake a better trading records, at least no math mistakes in it. Check my previous posts in HT, you will find my math is way better than 犀利妹妹.
