The most obvious thing is Uk's second statement. It's true, well, why else would the Grundi
throw a rock? :/
For the others...What if Tset was guilty?. It doesn't make much sense. Because He needs to tell
two truths. and two of them were basically saying he didn't do it. So..just..He's innocent.
So knowing that they have to tell two truths, the two statements that tset said claiming his
innocence must be them, because one cannot be a lie, or he'd be lying, and then their would be
two lies.
So He said Yan did it. Which is a lie.
Moving on to Yan.
He is innocent. Truth.
About the other ones, we need to go to Pala. Tset is
not guilty so that must be her lie.
Meaning the other ones are truths. So she has never seen Yan before.
Which means the truth for yan is thaa Uk is guilty!
I do hope this all makes sense

And I hope its right

EDIT: put the truth/lie marker in the wrong spot..durr.
