A fresh episode this close to the holidays? Yes, because Fox can’t burn off these final hours of Fringe quickly enough, even though, currently, it’s the network’s best drama. In tonight’s episode, Walter (John Noble) and the others try to jog the memory of a Boy Observer to glean more clues about how to save, and change, the world. Is it just me, or does this series have more memory-loss issues than The Golden Girls?
