WARNING: This article may contain spoilers for Outlander season 5 episode 10. Read at your own risk.

Outlander season 5 episode 10 is set to arrive later this week on Starz, with the title "Mercy Shall Follow Me." There is a major concern within this episode, as it looks like Stephen Bonnet returns and ready to cause chaos again. What's more terrifying is that he possibly captures Brianna.

In Outlander season 5 episode 10, Bonnet comes back and brings a new threat to the Frasers, especially to Brianna. But then, the family is ready to fight back, particularly Brianna's father Jamie and her husband Roger. Both of them are ready to track down and kill Bonnet.

In the previous episode, Jamie almost died after being bitten by a venomous snake. He feared that his end was close, so he asked and begged Roger to kill Bonnet whatever happens. Roger seemed to be reluctant at first, but eventually, both of them agreed to kill him.

In the trailer of Outlander season 5 episode 10, Rogers makes a request on Jamie. He asks him to teach him how to fight, saying he never killed a man or fought a battle. Although Roger says he's "no marksman" and only a "half-decent swordsman," he's still determined to take Bonnet.

They are preparing to take him down, alongside Fergus and Young Ian. Jamie is also impressed with Roger's progress. However, it looks like Bonnet is aware that Jamie and Roger are after him, as the promo shows him saying: "Darkness closes in."

Things may not go really well, as the clip also shows Brianna crying while wearing an extravagant ball gown. Her mother Claire, on the other hand, calls out in terror. The two are also seen at the beach, with Claire trying to figure out how to save her daughter.

The promo then shows a black boot stamp down on the sand, and Claire was shown in distance. Later on, she turned around and a pure terror is evident on her face. Brianna was also shocked when she realized the position her mother is in, Claire then told her to run.

There are only three more episodes left this season, so things could get even more intense leading to the finale. Bonnet could make the Frasers' lives difficult; he's capable of hurting other people. Another concern here is Brianna's son, Jemmy, as Bonnet might take him away from her.

Outlander season 5 episode 10 airs on Sunday night, Apr. 26, on Starz.
