S5·E9 The Gem of Empathy

An age-changing spell causes Stella to become a three-year-old girl. Musa, Flora, and Brandon look after her. Eventually, the spell wears off, reverting Stella to her actual age and appearance. Meanwhile, Bloom, Tecna and Aisha go to Tecna's home world, Zenith, to find the Gem of Empathy. Aisha and Tecna get into a fight and Bloom stops them as they have to work together to obtain the second Sirenix gem. They do so, and they gain the Gem of Empathy, leaving only one more challenge to gain the Gem of Courage.
