Revenge returns tonight, with the birthday party from hell! Daniel Grayson’s (Joshua Bowman) intimate celebration gets crashed by an unstable visitor.

And for those who watched last year’s final episode until the very last second — spoiler alert — know that it’s shady college pal Tyler (Ashton Holmes) who ends up pointing a gun at the Grayson gang, with Emily (Emily VanCamp) sitting right at the center.

“You know Tyler is a dangerous one,” Christa Allen, who plays Charlotte Grayson, told Wetpaint Entertainment.

“You saw he went off his meds, and it’s unpredictable what he’s going to do. You know how money motivates people, so for Tyler, it’s a mix of being insane and being driven by money.”

We already know, pretty much, which characters come out of the soiree intact, but that doesn’t mean the rest of the season is drama-free.

“I tell you we’re getting into winter now in the Hamptons,” Christa told us at the Golden Globes Night of Firsts.

“Winter’s approaching, and it’s going to get dark and snowy and colder than ever. As if Victoria (Madeleine Stowe) wasn’t frosty enough already.”

And although Christa reveals that her relationship with Declan (Connor Paolo) will “plug along,” her character Charlotte will soon be put in the middle of other turmoil – which likely has to do with her parents bitter divorce battle.

“It get so twisted,” says Christa. “Oh, what can I say without saying? We’re just going to drop a bomb on you in the next four episodes.  It takes a while to manifest.”

Lucky for Christa, behind the scenes, no one’s looking to imitate art and strategically ruin the tight-knit group.

“The people I work with are out of this world,” she tells us. “I can’t tell you the grace and manners that Emily exudes in her life. And Josh, everything he does, he approaches with the excitement of a six-year-old. Do you know what I mean?  And Gabriel – he’s  one of my best friends. It’s an amazing group.” {source}
