Role in the series
Nigel first appears in a non-speaking role in the episode "In Like Flynn", where he is seen alongside the Captain as King Frederic contemplates on how best to one-up his rival, King Trevor.
Nigel is seen again in "One Angry Princess", standing beside King Frederic and Queen Arianna as Attila the Pub Thug is put on trial for vandalism. When Rapunzel expresses Attila's right to a fair trial, Nigel informs King Frederic that she is correct.
In "The Wrath of Ruthless Ruth", Nigel visits King Frederic's quarters during a storm that has blocked all the roadways in Corona, preventing travel. Unfortunately, this prevents Rapunzel from returning home during her outing, which leaves Frederic in a depressed and worried state, which garners Nigel's sympathy.
Nigel also briefly appears in "The Way of the Willow", where Queen Arianna's estranged sister visits Corona for the first time in years, and apparently knows Nigel rather well.
With King Frederic and Queen Arianna left Rapunzel in charge of Corona while they were away in "Queen for a Day", Nigel helps the temporary queen with her royal duties. When a heavy snow storm hits Corona Nigel advised Rapunzel that they should move the people to the main land until the storm passes, and when Varian came to Rapunzel for help in Old Corona village while the people in the kingdom needed her more, Nigel got the guards to send the young alchemist away.
