SPOILER ALERT!

If you don't want to know anything about the Season 3 premiere of Heroes, then stop reading now.

E! Online has posted a brief spoiler about the premiere, which ties into the pics above.

"In the first three minutes one of the lead heroes is going to bust a cap off at one of the other lead heroes. And oh yeah, the guy she pulls the trigger on just might be the guy she's playing tonsil hockey with in real life. She also tells him (on cam), 'I always loved you.'" The spoiler also notes that she will be featured in a time shift as well.

Heroes is currently filming and Season 3 is set to premiere on September 15.
