Homeland star Morgan Saylor has hinted at "big changes" to come in season two's final episodes. The 18-year-old actress told The Los Angeles Times that she was "excited" and "nervous" to take on a bigger role in the Showtime drama's latest season. "It was a surprise," said Saylor, whose character Dana has become involved in a hit-and-run storyline. "My character got a little bigger at the end of last season, but this season I have my own plot-line. "It's crazy. Each script came out and it was juicier and juicier. And I was excited, but so nervous and scared that I wouldn't be able to carry it." Saylor suggested that her on-screen brother Jackson Pace - who plays Chris Brody - could similarly "step up" in the forthcoming third season of Homeland. "I know Jackson is eager to do something," she said. "I think as he gets older, there will be a little more juice able to be soaked up by him." Homeland's season two finale will air on December 16 on Showtime in the US and a week later on Channel 4 in the UK. "There are some big changes in the [Brody] family," Saylor teased. "We're kind of pushed to the limit."
