OK, maybe this week won't be completely doom-and-gloomy after all.

Sources confirm to me exclusively that the enchanting Brea Grant - who made quite the impression as Landry's short-lived rebound girl on Friday Night Lights - is joining the cast of Heroes next season as The Speedster.

As you'll recall, last month I reported that Heroes was casting the role of Joy, who's "quick on her feet - and adept at getting herself into and out of trouble."

Let me be the first to congratulate Tim Kring and his team on a job very well done. Who's going to be the second?
