Episode Three[]
Dorothy is willing to part her ways with Lucas, but they both end up at the castle of East, with Dorothy posing as the witch's pupil. After being asked to turn down his weapon by Sullivan, Lucas expresses his concern that he is not able to protect Dorothy from danger. Lucas is then distraught when Dorothy performs the Elements ritual and is taken away by the tornado.
When Dorothy returns from the place in-between unable to placate the weather, Lucas defends her against Sullivan and is almost killed. Dorothy pleads for his life and together they escape from the castle.

Episode Six[]
Determined to get his memories back, Lucas is willing to undergo torture. Anna's investigation reveals his memories are magically blocked, not repressed.
West uses her magic to determine that it was Glinda who locked Lucas' memories. Using Lucas' feelings for Dorothy, West manages to unlock some of the memories.
Lucas/Roan was transporting young witches, including Silvie when he was stopped by the Wizard's Guard. The threatened witches reacted by subduing some of the guards with magic and Lucas fought the rest of them off, but was wounded by Toby. He ordered the witches to run and took a pill to erase his memories.
His life now threatened by the Wizard, as he's been found the spy for Glinda, Lucas is freed by Elizabeth. The councilwoman is acting on Glinda's orders and procures a wagon for Lucas to escape in. Lucas finds Silvie to take to Glinda and Dorothy joins them on the trip.

When they meet Glinda, she is happy to see both Silvie and Lucas, whom she calls Roan and kisses him. The kiss returns him his lost memories: he no longer feels loyalty to Dorothy, instead he's bond to Glinda and want to join her on their quest to overthrow the Wizard.
Episode Eight[]
Lucas finds himself torn between Glinda and Dorothy, not fully back in his Roan persona. He helps Dorothy deliver Noa's baby. When Dorothy tries to murder Glinda, he intervenes and states that Dorothy would have to kill him first. However, he doesn't chase after Dorothy afterwards, which angers Glinda. Glinda gives him a knife and orders him to kill Dorothy to free himself from her spell.
In the works of L. Frank Baum[]
Dorothy finds Scarecrow in a corn field while walking along the Yellow Brick Road to the Emerald City.
Scarecrow joins her quest as he wants the Wizard to give him brains. Disemboweled by the flying monkeys, he reanimates once his clothes are filled with straw.
He becomes the king of the Emerald City once the Wizard leaves in a hot-air balloon and rules wisely for a longer while. After being deposed by general Jinjur, he escaped along with Tip and Jack the Pumpkinhead to Tin Woodsman's castle. He managed to get rid of JinJur with the help of field mice, who scared Jinjur away and was later tasked by Glinda to find a lost princess of Oz, Ozma.
After Ozma was found, Scarecrow stepped down from his role as a king and went on to live with Tin Woodsman.
His love interest in the books was a patchwork girl called Scraps.
Trivia[]
Lucas as the Hanged Man Tarot card.
- In the first version of the script he is called 'Henry', a name given to him by Dorothy. This was changed to 'Lucas' in the actual series, probably to avoid confusion with uncle Henry.
- The Facebook page of Emerald City pictured Lucas as a Tarot card The Hanged Man.
