I saw the film with my kids in the theater when it came out over Thanksgiving, and they’ve seen it several times since its debut on Netflix in July – and it’s quickly become the third most streamed film on the platform. With each viewing, I find the mood enchanting, the music catchy, and the plot forgettable. But it wasn’t until recently that my 9-year-old pointed out to me that, in addition to forgetfulness, there is also a great Trolls 3 Plot hole.

Listen to me: In Trolls 1we learn that Branch (Timberlake) is so grumpy because he was traumatized by the death of his grandmother, Grandma Rosiepuff, at age five (via Bergen-Eat). In fact, he was so distraught that he vowed never to sing again.

And yet Trolls join forceswe learn that he was actually singing again! As my son noted, after Branch’s first band Bro-Zone broke up, he joined a second band called Kismet, this time featuring the aforementioned singers from NSYNC. The timing of Bro-Zone makes sense: Branch, who sang under the moniker “Bitty B,” was apparently a baby at the time, before he experienced his grandmother’s death at age five. But things get more puzzling when you consider Kismet, a band he was apparently in when he was older than a kindergartener. Did he join this band between the events of ? Trolls And Trolls World Tour? Did he leave Bro-Zone when he was still in diapers, join a second boy band (this time as a heartthrob) and then give up singing? Did he actually sing a little between Granny’s death and meeting Poppy?
