Spoiler releases for the January 21st episodes of “Grey’s” and “Private Practice” follow . . . . Highlights include the second return of Izzie on “Grey’s” and Maya delivering shocking news to Sam and Naomi on “Practice” . . . My initial guess is she’s pregnant, but that’s too easy I think, probably just that she’s having sex.
