"Falling Skies" is between seasons and is currently filming its season 5. The fifth and final season of the show will be ten episodes and likely will premiere next June. 

Oscar-nominated Catalina Sandino Moreno will have a recurring role in the final season of Falling Skies. She will play Isabella, who was a left leaning academic prior to the invasion, but has since become a hardened pragmatist.

CarterMatt reports, "For the time being, though, we can at least give some more information regarding who will be a part of it. As first confirmed by show star Sarah Carter on Twitter (see below), Catalina Sandino Moreno is going to make some appearances on the TNT series. According to TVLine, she will appear in the second half of season 5 as Isabella, a driven and very-tough woman who will do anything to survive.

Specifically, expect her to spend a ton of time with the Pope character, and work undercover as a nurse while trying to ensure that he and her are on the same side. There are clearly many things about her that remain enigmatic, but we definitely do expect this to be a fun addition to the show. After all, Isabella is a character with a big heart, and that will become clear as we get further and further along into the story

CarterMatt points out that the plot entering next season will probably be filled with hope.

"In terms of broad strokes, what we do anticipate from the final season starts and ends with one word: Hope. While we've seen our fair share of shows with sad endings as of late (from Breaking Bad to Dexter to even How I Met Your Mother, mostly in that it wasn't any good), we cannot imagine that this will be one of them and leave anyone satisfied. After all, what would be the point of the past several years just to see them suffer more at the end? This is not like Walter White, where he was a terrible person for most of the run and really got what was coming to him in so many ways. Tom doesn't deserve to be gunned down or destroyed," it said.

"Also, we do expect some cast shake-ups (characters do die), some further information about the Espheni and other alien races, and what a potential human society could look like now that so much as changed."

According to The Wrap, Taylor Russell will join the cast. The only thing we know about the character Russell is playing, Evelyn, is that she will be taken in by the 2nd Mass "when she's found roaming.

When season 4 ended, Tom was facing something unknown he called "beautiful," and Noah Wyle told us that "the payoff for it next year will be worth it."

Showrunner David Eick did tell Entertainment Weekly that this will set up an "internal" and emotional story for Tom as we get near the end of the season:

"I'm not at liberty to deliver fully disclosed spoilers, but I will tell you that what Tom does see will prove to be the sort of lynchpin in what drives [the 2nd Mass] and provides a strategic angle for the 2nd Mass to pursue in the fifth season. I wouldn't say they discover a doomsday device, but what they discover is a strategic weapon of sorts that will prove to have a great impact on what happens in the fifth season."

"It is a more emotional, internal motivation that propels Tom Mason in season 5. It's not just about tactics or looking at war room maps, although that remains a big part of the show. It's about how even the best generals will tell stories about how they had to rely on their gut, and [season 5] is a season in which the gut aspect of Tom Mason's approach to defeating the enemy takes on a much more prominent role via the encounter he has at the end of season 4. So through that encounter we will emphasize the emotional aspects of his decision-making, his strategy, and the ultimate outcome."
