Secretive and quick to adapt, the mermaids of Bristol Cove always keep us on our toes. Check out our picks for the mermaids' most surprising moments in Siren season 2, and don't forget to stream them now on Freeform.
1. When a new group of mermaids unexpectedly arrived in Bristol Cove.
Helen must have thought she was dreaming.
2. When we discovered Cami's lineage.
And just like Donna, Cami has an incredibly fiery spirit.
3. That time Levi showed off his epic beer pong skills.
Mermaids are fast learners.
4. Not to mention when he started to glow.
Which we learned meant it's time to make more mer-babies.
5. Watching Eliza and Rick meet for the first time.
Their gentle side always catches us off guard.
6. And when Sarge and Helen first realized their connection.
We knew Katrina couldn't be trusted, but things took a really dark turn when Cami decided to seek revenge for Donna's death.
8. But Ryn and Katrina eventually put their differences aside and became allies.
While they had to fight the real enemy together — Klesco Oil, it was a big turn in events.
9. This moment when they came together to thank the humans for helping them.
Not surprising: Katrina's reluctance.
10. When they discovered a cave where humans and mermaids had once lived in harmony.
The ties between land and sea were deeper than we imagined.
11. Cami shocked us again when she couldn't let go of her quest for revenge.
And in the process, almost took out Xander and Calvin.
12. The most heartbreaking moment of the season.
Sarge sacrificed himself to save his pack. And no, we have not stopped crying.
13. When Levi unexpectedly returned to land.
Clearly Levi's human legs were built for dancing.
14. And when Eliza delivered some worrying news about the future of the mermaid species.
Hopefully we'll be seeing some mer-babies in the future ...
