BREA GRANT
Heroes (Mondays, 9 p.m., NBC)
WHERE YOU'VE SEEN HER: Using her geek-girl charms to woo Landry as Jean on Friday Night Lights.
WHY SHE'LL BREAK OUT: How could we not get behind a FNL alum? Plus, Grant's new gig on NBC's hit sounds intriguing: She's a villain nicknamed ''Speedster'' (real name: Daphne), who proves a worthy adversary to time-traveler Hiro.
