He's lying, he's not sorry.
The classic riddle has the caveat that you are only allowed to ask one question so how is asking "what's 2+2?" going to let you know which door to take?
The solution being, for the singular person on Earth who hasn't heard already, "If you were the other guard, which door would you say is the safe one?"
Alternatively, the barbarian in the party just splatters one of the guards in one hit and asks the remaining one, "Which door? You'll go through it first."
Alternatively: the one that explained the riddle is a liar, and they both lie.
Is it just one question or one question per?
Just the one question. Here is the wiki on this riddle: https://en.wikipedia.org/wiki/Knights_and_Knaves
Thanks! I was suddenly ashamed that I’d never thought of this until you pointed this out.
What if G1 is lying and both of them always tell lies?
Or the "only" part is the lie?
