Troian Bellisario is here to tease for “Pretty Little Liars” fans what to look forward to on next week’s Halloween episode, “Grave New World.”

“The girls are now chasing Red Coat and Red Coat has led them to Ravenswood. We know the closer we get to Ali, the more dangerous it becomes with ‘A’ and so that’s what gives ground to these massive fight sequences and big action sequences,” says Bellisario. “‘A’ is not playing a game anymore. It’s really life or death.”

She adds that Spencer is definitely going to have her kick-butt moment of the Halloween episode.

“The girls are all kinds of damsels in distress every once in a while, and then they choose to fight back,” says Bellisario. “Spencer’s getting scared and backed into a corner and is ‘A’ gonna kill her? And then she just kind of turns around and picks up the garden shears and is like, ‘Let’s do this.'”

“Other than the finales, this is definitely going to be the most fun episode of the year. … So many mysteries will be revealed. It’s just fun, you know? It’s a scary movie,” teases Bellisario.

“Pretty Little Liars” Halloween episode airs Tuesday, Oct. 22 at 8 p.m. ET/PT on ABC Family.
