LoliRock S02E17 - Truth Be Told

The twins use a voice changing crystal to trick the Lolirock girls to meet at different places, but when they ambush Iris, a mysterious masked woman using crystal magic drives them away. The girls find a necklace at the battle site but are unable to trace its owner, that is, until Iris brings it home and discovers the necklace is drawn to Aunt Ellen. Iris learns that Ellen is actually an Ephedian royal guard named Ellira who was tasked by Iris's mother to take care of and protect Iris on Earth. Iris and Ellen help the other two girls defeat the twins.
