Surprise, surprise, Cole has turned into a bad boy again and is once more staring his evil side in the face and enjoying every second of it.
Piper, however, is a little too busy to worry about Cole and she has developed an alarming new power. Whenever she gets stressed and throws up her hands, instead of things freezing, they are being blown up! It is rather amusing to watch her try and control it, but even more so, watching Leo and the others try to keep her calm so that she doesn't start a major catastrophic event.
Not a bad episode, and the introduction of the new power was a good idea, but it wasn't a stellar one either, particularly as it's near the end of the season.
