WARNING: This article may contain spoilers for Siren season 3 episode 8. Read at your own risk.
Siren season 3 episode 8 is set to arrive next week on Freeform, with the title "Til Death Do Us Part." There are only three episodes left this season, so things may accelerate further from here. Entering this episode, Ryn and others have to deal with Tia, as well as her army.
Tia has been one of the biggest adversaries within the series, putting Ryn in a delicate position. Now, it looks like things wouldn't get any easier and they need to protect what they have. The synopsis of Siren season 3 episode 8 notes Ryn, Maddie, and Ben needs to protect Bristol Cove from Tia's army.
Tia is the newest mermaid this season. She came from different colonies of the northern seas around Bristol Cove and humans called her as "sea monster." Her main intention of arriving on land is to coerce other mer-people tribes to join her as she wants to end the human race.
Now that her motives are clear, Ryn and the rest need to do whatever they can before Tia could destroy Bristol Cove and its people. She also knows about Ryn's mer-baby and threatens her with death if she doesn't join her and her colony.
The previous episode, titled "Northern Exposure," featured a new place and introduced another mermaid clan. Robb is a mermaid. He comes from an isolationist clan in Alaska and Ryn knows he's a skilled warrior. She also recognized that Tia reached out to Robb's people for help.
As for what else is coming in Siren season 3 episode 8, Ben's injections are producing unexpected results, which leads to him and others to panic. Xander, on the other hand, juggles his best man duties at Calvin's wedding while helping Helen at the same time.
The episode title likely referenced to the wedding storyline. Something big and dramatic may happen here, considering that it's a huge event. There are probably unexpected moments moving forward and could likely set up more stories leading to the season finale.
Meanwhile, although there are a handful of episodes left this season, it should be noted that noting is confirmed when it comes to the future of the series. Freeform hasn't yet officially renewed or cancel Siren, so viewers may need to wait for a while for the renewal announcement.
Siren season 3 episode 8 airs on Thursday night, May 14, on Freeform.
