How would a spin-off 20 years after the finale go?
Some of my headcanons:
• Cleo and Lewis would both be biologists who had a successful career abroad, but their daughter is going through mermaid-related changes so they moved back home so she could be closer to Mako.
• Rikki stays running Rikki’s café, and “dives” on the side (as seen in Mako Mermaids).
• Zane becomes a finance bro who lives in the city, but will still always have a soft spot for Rikki.
• Emma is married and has a son; although her husband knows her secret, she hasn’t gone near the water in years. Being with the girls again reignites her love of the water.
• Bella and Will broke up shortly after graduation. Bella is a high school music teacher, who tries to write her own music but it always falls flat and she struggles to find inspiration. Being with the girls and being one with the water with them again gives her the inspiration to write beautiful music.
