Fans of Eric Wald and Dean White's Siren will have some time to debate the ramifications of the second season finale of Freeform's mermaid fantasy-action drama before it returns for a third season, but we're learning who will be joining Ben (Alex Roe), Maddie (Fola Evans-Akingbola), and Ryn (Eline Powell) to face Bristol Cove's – and the mankind's – new world order. Deadline Hollywood is reporting exclusively that Tiffany Lonsdale (S.W.A.T.) will join the series as Tia, an extremely intelligent mermaid with a highly evolved knowledge of the human condition. She speaks several languages, understands advanced science and technology, and was trained as a high level warrior.
Here's a Look Back at Freeform's "Siren" Season 2…
In the second season of Freeform's Siren, more mermaids arrived in the once-sleepy fishing town: some seeking revenge, some looking to explore – with something catastrophic driving them out of the sea. Ben and Maddie continued to establish a bond with mermaid Ryn – not just to protect her but to save her entire civilization.
Freeform's Siren is based on a story by Eric Wald and Dean White, with Emily Whitesell (Finding Carter) serving as showrunner. Wald, White, and Whitesell join Brad Luff, Nate Hopper, and RD Robb as executive producers.
"Siren" takes us inside Bristol Cove—a coastal town known for its legend of once being home to mermaids. When the arrival of a mysterious girl proves this folklore all too true, the battle between man and sea takes a very vicious turn as these predatory beings return to reclaim their right to the ocean.
The series stars Alex Roe ("The 5th Wave") as Ben, a bright marine biologist who finds himself drawn to Ryn, a mysterious new girl in town played by Eline Powell ("Game of Thrones"), who is a strange young woman with a deep dark secret. Fola Evans-Akingbola ("An American Exorcism") stars as Maddie, also a marine biologist who works with Ben, and is highly suspicious of Ryn. Ian Verdun ("Life's a Drag") stars as Xander, a deep sea fisherman on a quest to uncover the truth; and Rena Owen ("Star Wars" Episodes II and III) as Helen, the town eccentric who seems to know more about the mermaids than she lets on.
Ben and Maddie are uncertain about the mermaids' future after the deadly consequences of the attack on the oil rig and, with the mermaids returning to sea, are left feeling lost without Ryn. Once Helen learns she's not the only one of her kind, she discovers there is a dark side to her people's past.
Freeform's Siren aired its second-season finale earlier this month, and is expected to return for a third season some time in 2020.
