>>10136215Albert says to Bernard that he knows that Bernard doesn't know.
Bernard would only know for certain if he was allocated 5 or 6. Which tells Bernard that Albert must have either C or D.
So we know that Albert is either C or D and Bernard is either 1, 2, 3, or 4.
Bernard's reply then suggests that, just based on knowing if Albert's pad is C or D, he can then determine the correct pad. Only if Bernard had 1 would he not be able to determine it.
So we know that Albert is either C or D and Bernard is 2, 3, or 4.
But when Albert then confirms that he also knows the correct pad, this cancels out D as that has the two options of 2 and 4, preventing his certainty.
Thus, Albert is confirmed to have C, making it so that Bernard must have 3.
It's C3.
Please tell me I'm right, Anon.
