The slow possession of Sam by Himiko
Sam and Lara were astonished to receive a ransom tape from a Mexican gang called Las Serpentes Que Caminan in which their friend Grim -thought to have been killed on Yamatai – was being held hostage.
Since the women didn’t have the money to pay the ransom, Sam came up with a plan for them to travel to Mexico, using the cover of shooting a documentary about the Chupacabra (along with Jonah and Alex’s sister Kaz). Sam also asked two of her friends to pose as herself and Lara while they were away to avoid drawing suspicion.
On her way to the Island where Grim was supposed to be detained, Sam started to act strangely, snapping at Lara when she wasn’t suffering from moments of absence. As a storm rose, Sam jumped into the water and came face to face with a shark. Unfazed, she stabbed it in the eye with her necklace until Lara dragged her out of the water.
They reached a village and started shooting the documentary about the Chupacabra as part of their cover, at which point, a local woman realized Sam was possessed.
Lara became increasingly worried after Sam passed out and tried to question her friend about her behavior but Sam once again snapped at Lara, telling her to stop treating her unfairly like she had been ever since they returned from Yamatai.
As Lara went to find Grim, Las Serpentes Que Caminan captured Sam, Jonah and Kaz. Lara and Cuddy Grimaldi – who was in fact Grim’s twin brother and not the dead helmsman – rescued them, but in the middle of the fight, an enraged Sam suddenly grabbed a machete and killed one of her captors. Much like the incident with the shark, Sam had no recollection of the incident.
As the team left the Island, Sam settled in a room on the boat. In a near catatonic state, she stared at the mirror but instead of her reflection, Himiko was grinning back at her. Despite Lara interrupting the ascension ceremony, Himiko had been able to transfer a small but growing part of her soul into Sam’s body.
