Hello, since nothing is known about Alpha and Omega 5's plot I decided to make my own prediction for fun. Before I begin I will state that some of this idea came from a Fanfiction that's being written por "jhiliton0907." His story is kind of inspired por Rio 2 as well. So while it's not entirely my original idea I realized that it could actually work out as a plot to end off the series. Here it is;

As the pups begin to mature and near the end of their schooling, Kate and Humphrey decide that they should take one last trip as a family while they still can. After growing curious about where he came from and where his parents are, Humphrey suggests that they should take the opportunity to look for his parents. Everyone agrees and the buscar begins, with the only lead coming from Winston who says that their somewhere back in the states (I'm not going to get into too much detail). After a few days they end up coming across a new pack that is inicial to none other then Humphrey's parents. It's a joyous reunion for everyone, however things get cold when Humphrey's father realizes that his son married an alpha. He doesn't trust Kate because of this, thinking that dado the opportunity she would leave him for someone strong and well built. And being his father, he doesn't want anything bad to happen to his son now that they've been reunited.

He comes up with a plan to secretly test the loyalty of their relationship por putting them in difficult situations, both physical and emotional to see if they would reach a breaking point. At the same time Humphrey's mother, who agrees with the idea, decides to keep the pups busy while this happens. Kate and Humphrey succeed in the tests, unknown to them that they are being set up. However something life endangering happens to Humphrey because of the tests, and while this happens their pups discover that his father is behind it all, and is now left to deal with a furious Kate and Humphrey after she jumps into action and saves her mate. Humphrey gathers his mate and pups and decides to just leave and head home, losing all his respect for his parents after learning that they would even think of testing his and Kate's relationship like that.

Along the way inicial Humphrey has a breakdown after thinking about his parents actions and while this happens his father and mother appear after following them all this way. His father realizes his mistake and how wrong he was to test his sons relationship and pleads for his forgiveness. It takes some persuading but eventually Humphrey, and Kate, forgive them both. The movie ends off with his parents joining the western pack and giving Humphrey the closure he wanted.

There tu have it, of course this is just a brief summary of it all and can be expanded greatly, but if done right this could turn into an amazing movie. A movie that could give Kate and Humphrey the focus they deserve while still leaving screen time for their pups and other original characters towards the beginning of it. It may seem a little dark in some areas but after A&O 4 it's obvious that it's still possible. All of this could fit into a 45min movie and serve as a fitting ending to the series as a whole.

But this is only my theory, we'll have to wait and see what Crest actually comes up with in a few months time. Until then, let me know what tu think about this, good idea o too complex and unentertaining? -ChriZ
