Why no one recognises LLH as LXY

This topic keeps resurfacing in the comment section.

I like to keep a discussion here so new people can see it.

People, they did recognize LLH. But since they believe LXY is dead and LLH is doing all he can to stay "dead". They try their best to test him, to get him off guard, to catch his lies. But we have a master liar here. 

His sect believed LXY was dead because, to them, they see no reason for LXY not to return to the sect. We know LXY did and seeing how they react and from the guilt from causing people suffering and sect members death, he decided to stay dead.

They tested him to see whether LLH was LXY because he looked just like their dead leader. Again, they did recognize him. But on the other hand, we have LLH doing his best to fool them that he is dead.

Once LLH fooled them, to the sect people, LLH was just a man who eerily looked so much like their dead leader.

LLH fooled them at the beginning, but they did recognize him in the end. His small habits blew his cover.

DFS recognized his enemy right away, the same as LLH recognized DFS even when he disguised himself as a kid. But to those two, the world's recognition meant nothing. DFS just wants to fight LXY, and LLH wants DFS to tell him about his brother's burial.

In episode 3, the monk who treated LLH with "golden needles" said the treatment could only recover a tenth of his "inner skills"/martial arts skills and would change his appearance making others unable to recognize him. 

Yes. But in the drama, LXY and LLH is being played by the same person. With no ageing added to change his appearance.  That's why many asked why no one recognises him. While in fact they did.  

MLC relies on logical deduction to solve the mysteries, hence some expect the biggest mystery should be why no one recognises LXY.

The voice actor is also different that they have for the younger LXY, so he sounds different. I thought that was a nice touch :)

He subtly looks different and his mannerisms/posture and way of speaking are different. LLH listens more and is quiet preferring to be an observer. LXY was boisterous liking to be the center of it all. LXY laughed a lot and was forceful in his actions. LLH is more reserved and careful, hiding behind a mask (quite literally in some episodes).  He is so different 10 years later that even DFS tells him so multiple times when they speak. I think the point is that he doesn't LOOK completely different, but he looks different enough like the Monk said.  It is the combination of voice change, aging, demeanor, and how he thinks now. It is all ENOUGH to make people doubt that he is really LXY, not to mention noone recognized him outright. Not even DFS.   DFS was only sure it was him after LXY did his whirling steps skill after the entire tomb drama.  He may have suspected earlier like when he tossed that knife past him as a test at the table when he looked like a kid, but LLH didn't react like LXY would. Likewise, LLH's ex only got sus after some little mannerisms such as tapping of the spoon similar to tapping of his sword, but even then she wasn't sure until the poison miraculously was cured. The others at the sword revealing ceremony were oblivious.... only sus for maybe a glimpse of a  smile or a gesture that triggered memory.  LLH did not behave like LXY. I really like the scene in the mine where LLH was trying to rescue FDB from the twins; LLH changed his demeaner/posture and even spoke as if he were LXY, bluffing his ass off.  I found it funny that LXY was really just LLH pretending to be LXY. He really *is* LLH (not LXY anymore).

But I also think it may be a little self delusion on the part of all the people who used to know LXY in the past. They didn't WANT LLH to really be LXY because then they'd have to face the reality of WHY he didn't come back (meaning they would question if it was their fault).  Wasn't he being dead easier than facing their own guilt/mistakes/insufficiciency? They seemed more than happy to grasp onto LLH's lies (even the obvious silly ones....like he had a twin) and to 'play along' with the story that he is someone else. Noone likes to be wrong or to face someone they feel they wronged.....guilt (or even jealousy) can make us behave in weird stupid ways.  LLH was only trying to fullfill their desire for him to indeed be dead.
