I have a few questions on Episode 38: 
but first, Recap: 

(1st) accuse weiyoung of being a Jinx, have her beaten till she fell ill, dispose her to wolves. 

(2nd) steal the disaster relief plan = own brother died

(3rd) Expose Weiyoung's fake identity = was stripped of her household's power 

(4th) witchcraft 

(5th) witchcraft’s inception = framing the framer = Male cousin's mother got killed

>>>> I want to ask a few questions:

In (3rd) which is in Episode 14, did prince of GaoYang know that the Chiyun family has an artist of disguise skill?
I don’t remember him knowing this at all.

In ep34, when weiyoung was framed of killing his mom, she didn’t tell him about the disguise trick either.  

So where the heck did 27:00 in the episode come from? when and where did he get that info?
if you watch the episode again, it was at exactly 27:00. 
Is this the writing's inconsistency? 
About to watch that episode but if it doesn't show the moment he found out, when he snapped out of mourning he sent his servant to investigate thoroughly. He may have found out this way
