A native, either a knight or a liar, once pointed to a man sitting below a tree and told me "If asked, that man would say I'm not the same type as he is."
What can you deduce about the native or the man?
If a knight (truthful) is speaking, then the man in the tree is a LIAR.
If a liar is speaking, it is not truthful that man in tree would deny being the same as him; therefore truth would be that man in tree would say they are of the same type and is a LIAR.
LIAR either way.
