Tom Mason will have to make a huge choice this week.

In the next episode of "Falling Skies," Tom (Noah Wyle) will have to make a decision that could result in the death of a character. The next episode of "Falling Skies," titled "Hatchlings," will focus on hard choices, alliances with allies and underestimating the enemy. Here is the synopsis for the next episode below via CarterMatt:

"The 2nd Mass makes a discovery about the source for a seemingly endless supply of enemy forces. Elsewhere, Tom's leadership spreads to remaining human militias; Hal helps Maggie on a personal mission; and Tom must make an agonizing choice."

Tom will also team up with The Volm. The other subplot in this episode is Hal (Drew Roy) disobeying his father to help Maggie (Sarah Carter) on a personal mission.

This upcoming episode is hinting that a minor or major character will die. The question is who will perish?

Wyle explained in an interview with the New York Daily News what the good and bad parts were of filming "Falling Skies." He stated: "I'm really proud of how we did the show, It feels authentic. It's had a real grit and verisimilitude you don't always see on television productions."

As for the bad part, he said: "When we started shooting the last season, I looked at the script, saw that scene and said okay, that's good, we can film that in the summer when it's warm. It won't be too bad."

He continued: "Well, it turned out we couldn't. It was the last thing we filmed, in November, and the water was freezing. What you see with me crawling across those rocks is the one and only take. What you would have seen if the camera had kept rolling was me standing up and yelling, 'F--- this!'"

The next episode of "Falling Skies" airs this Sunday at 9 p.m. on TNT.
