Carpe Demon

When Paige attempts to hire a new professor for Magic School, she learns that one of the candidates, Drake, is an ex-demon who made a deal with a demonic Sorcerer to become human.  In an attempt to convince the sisters of his good intentions, Drake transforms himself into Robin Hood to help them see that life is not so bad.  However, the Sorcerer vying for Drake's powers casts a spell on him causing Drake to believe he really is Robin Hood.  Convinced that Phoebe is "Maid Marion" and the corrupt owner of the phone company is the evil "Prince John", Drake takes him hostage, causing a media frenzy.  Meanwhile, Piper can't enjoy Valentine's Day knowing that Leo's fate is in the hands of the Elders.
