All hell is about to break loose on Colony, and the fallout from Katie's train bombing will scatter the Bowman family in every direction.

Will (Josh Holloway) and Katie (Sarah Wayne Callies) are fighting for their children's safety, albeit in drastically different ways. While Will wanted to get the hell out of Dodge, Katie believes the residents of the Los Angeles bloc need to stay and fight. In the wake of "Zero Day," violence will erupt on a scale unseen since the Invasion. As Maddie (Amanda Righetti) flees to the Green Zone with Hudson (Cooper J. Friedman) and Gracie (Isabella Crovetti-Cramp) in "Gateway," Katie will have to decide if the risks were worth it (check out the sneak peek below).

"I think Katie's perspective is it's not enough to just raise children. You have to raise children that are free," Wayne Callies said during a conference call with EnStars.

For the youngest members of the colony, memories of the past are quickly slipping away. It's only been a year, but for a child, 365 days is an eternity. Now that the Transitional Authority is inculcating the youth into a cultish existence, Katie has more reason than ever to push back at the RAPs.

"You see it in her daughter that this little girl is getting used to it. She's only eight. And so, her memory, the longer this goes on, her memory is more and more a memory of checkpoints and breadlines and curfews and people being afraid of their government," Callies explained. "And I think Katie feels very strongly that the greatest act of love is fighting for her children's intellectual and creative and spiritual freedom."

Even if the Bowman's escaped to Big Bear, they would never be truly free. As Los Angeles erupts into chaos during the finale, Katie will have to decide if the benefits outweighed the risks.

What do you think? Should the Bowman have ran to Big Bear when they had the chance, or should everyone be doing their part to secure the future of the human race? Sound off in the poll below!
