About Char X Quest

[Nightclown]

Back when i did the mega char x quest, i showed the npc first two poke then on the third one i got  super mad and spammed a wrong poke after which the npc battled me.

I beat him up and he gives me the Char X mega stone. Now, yesterday someone was having trouble on third poke i suggested him to do the same but it didn't work for him.

Anyone else who has done the x quest like i did? Was it removed? or Was it a Bug?

 

Also if someone(Who has shown all 3 poke) can link a screenshot of what the npc says after u interact with him then it would be great. Thanks 

Here is what npc says when i interact with him.
