"Sister of Invention" is the fiftieth episode of the Disney Channel animated series Elena of Avalor. It premiered on October 7, 2019 and is the first episode in the third season.

Plot[]

At Avalor Palace, the Royal Family and their friends are having a party to celebrate Isabel completing her Engineering Class with honors. Suddenly, Gabe comes in and tells Elena "He says he'll talk but only to you." Isabel notices Elena and Gabe leaving and asks what's going on. Elena tells her it's nothing for her to worry about and leaves with Gabe.

Elena and Gabe head down to the dungeon and arrive at Victor's cell. Elena asks Victor what he has to tell her. Victor merely tells her that it's to inform her that he'll tell her nothing. Elena tries to get him to tell her where Ash and Carla are but gets nowhere until she mentions the Delgados' Cabin. Realizing that the Delgados didn't know they discovered it, Elena decides to ambush Ash and Carla at the Delgados' Cabin. Elena sends Gabe to fetch Naomi and Mateo. Isabel notices Naomi and Mateo leaving and follows them after grabbing her Go-Pack. Isabel uses one of her inventions to eavesdrop on Elena's plans. However, Gabe notices and exposes her. When Elena confronts her, Isabel voices how she wants to come on the grounds that she has inventions and gadgets that can help and that she can handle herself as she's been to college. Elena refuses both because it's dangerous and her belief that Isabel will just get in the way and sends her back to the party. Undeterred, Isabel changes into her hiking outfit and climbs inside the luggage rack on the Royal Carriage where she falls asleep after it sets off. 

The group arrives at the Delgados's Cabin. Elena, Naomi, Gabe, and Mateo surround the cabin. Isabel wakes up and gets out of the luggage compartment. Elena hears her and sends her friends in. Naomi, Gabe, and Mateo only end up attacking each other as Ash and Carla aren't there. Back outside, Elena is shocked to see Isabel and is angry at her, to the point where she calls her by her full name "Isabel Castillo Flores". Isabel doesn't even notice her big sister's displeasure as she's too busy examining little blue rocks which she traces to the cabin while being folllowed by Elena who is furious both because Isabel isn't even listening to her and because Isabel is walking away while she's still talking to her. Isabel tells the group that the blue rocks are lava rocks that only come from one place: Xotep, a volcano in Central Avalor that known for it's eerie blue lava. The group tells Elena to let Isabel stay especially after she reveals she has a map to Xotep. Elena agrees on the condition that she stay in the coach. 

At Xotep, Ash and Carla have indeed shown up there and have met the Malvago who trained Ash: Zopilote. Ash asks Zopilote for new tamboritas, but he instead gives Ash a puzzle map that reveals a map to Takaina, the crystal forge where the Maruvians used create their mystical treasures and artifacts, including the Scepter of Light. Ash tells Carla to practice her tamborita while she solves the puzzle. Outside, the blasting draws the attention of Elena's group. Isabel suddenly gets off the coach and capture Carla with her invention, only to lead to the situation where Mateo messes up his spell and causes Elena to dangle from a cliff. Her friends try to save her in different ways, but none of them work. Meanwhile, Isabel calculates the distance of the rope to the cliff and comes up with an idea to make a catapult with rocks. She informs the group about this, and the group rescues Elena using what Isabel explained to them while the Delgados escape. Elena thanks her friends for saving her, to which they say it is really Isabel who she should thank since she is the one who came up with inventions to save her. Yet, Isabel feels guilty that she is the one who put Elena in danger in the first place and admits that she can't do what Elena and her friends do. Elena is glad that Isabel finally sees that, and encourages her by saying that they can't do what Isabel does, either (saving others with inventions). She welcomes Isabel to the team but still grounds her for disobeying a royal order.
