I read somewhere that Pierce's proclamation that he nailed Eartha Kitt in an Airplane bathroom in the prior episode was in fact due to that being filmed and intended to air after Chaos Theory, but was in fact aired beforehand.
However, have you noticed how the episode starts with Annie and Britta saying "303. You sure its not 304? No I wrote down 303. Twice."
Notice how this was Episode 304? Apparently supposed to be 303 but was in fact 304 contrary to what Annie believed?
There is some serious shit here folks.
We're through the looking glass people.
