Falling Skies John Pope is a solitary creature, but the most rebellious member of the 2nd Mass will change his tune now as season 4 progresses.

Pope (Colin Cunningham) found a kindred spirit in the form of Sarah (Mira Sorvino) during "Evolve or Die," and this new bond will make the hardened pragmatist.

"The interesting thing that they've done with season four is they have thrown in a love interest. So now Pope isn't entirely out for himself," Cunningham explained to TV Wise. "The strength of Pope is that he's not encumbered by a kid or a girlfriend, but they introduce Mira Sorvino's character Sarah this year. All of a sudden you begin to see the cracks in Pope a little bit and he now has a vested interest in something other than himself and that creates an interesting dynamic."

However, Pope's newfound ability to care for others will not extend to Lexi (Scarlett Byrne). While tom Mason (Noah Wyle) may want to protect his daughter, Pope will have no problem voicing his concerns about her clearly dangerous nature.

"[Lexi] becomes a real threat, so much so that Pope's ambition is to take this kid out," Cunningham said, according to TV Wise. "Lexi is Mason's blood, so he's caught between seeing the logic of how dangerous this young girl could become and the fact that it's his own flesh and blood. Pope only sees her as an absolute threat and he's going to try and take her out any chance he can get."
