In the concluding half of Charmed's fifth-season opener, Phoebe (Alyssa Milano) has elected to remain in the form of a mermaid -- partly because she wishes to escape her marriage to ex-demon Cole (Julian McMahon), partly because, well, she likes being a mermaid. Although she has vanquished the infamous Sea Hag, Phoebe is still in danger, courtesy of the Hag's demon ally Necron (Judson Scott). As Paige (Rose McGowan) and Leo (Brian Krause) encounter enormous obstacles in their efforts to persuade Phoebe to return to her human self, Piper (Holly Marie Combs) attempts to overcome her crippling panic attacks by casting a "fearless" spell -- which, alas, backfires horribly. ~ Rovi
