Ep 7. To Catch a Changeling

The animated series Trollhunters introduces viewers to Jim Lake Jr., a typical teenager who inherits a mystical amulet that transforms him into a powerful troll warrior. Throughout the first season of the show, Jim navigates his newfound powers while fighting against a race of malicious trolls determined to destroy the human world.

In episode 7, "To Catch a Changeling," Jim learns that not all trolls are bad when he encounters a changeling - a shapeshifting creature who has taken the form of Barbara, his friend's mother. At first, Jim is unsure of how to approach this situation as changelings have been known to deceive and manipulate others for their own gain. However, as he spends more time with Barbara, he begins to see that there is more to her than meets the eye.

Meanwhile, Jim's troll mentor Blinky and his sidekick AAARRRGGHH!!! are hot on the trail of the changeling. They enlist the help of Toby, Jim's best friend, to help them find and capture it. However, their search becomes complicated when they discover that the changeling has taken on the form of a well-respected police officer. The group must tread carefully to avoid tipping off the changeling and to ensure that they can safely apprehend it.

As the episode unfolds, it becomes clear that not everyone in the group is on the same page about how to handle the changeling situation. Some members are eager to capture it and turn it over to the Troll Tribunal for punishment, while others - including Jim - are more empathetic and want to understand its motives before taking any action.

"To Catch a Changeling" is a pivotal episode in Trollhunters because it marks a shift in Jim's understanding of the troll world. As a human, he has been conditioned to see trolls as dangerous monsters who must be fought against at all costs. However, his encounter with Barbara the changeling opens his eyes to the fact that there is more nuance to the situation than he initially thought. This realization sets the stage for future episodes of the series, in which Jim will have to grapple with the moral complexity of his actions as a troll warrior.

Overall, "To Catch a Changeling" is a suspenseful and emotionally resonant episode that explores the gray areas of good and evil in the Trollhunters universe. Viewers will be on the edge of their seats as Jim and his friends race to capture the changeling, and will be left with plenty to ponder after the credits roll.
