Nathaniel finally realizes what exactly is going on with Craig after all these years. Is Craig toxic, sure. Is Craig also suffering from a chemical imbalance, you betcha. Although, Nathaniel believes there's a little extra in there messing with Craig's psyche. The B plot  of Voices Carry is a mess. Just pure cringe. We unfortunately have to cover Bark at the Moon as well which is HEAVY most things wrong with season 4, Chester, Mr. O/Paige.. etc.
