You were exploring an island you went for fun, you were rich and decided to spend money on a boat and come here, expecting no one, you explore freely with no worries. Meanwhile...Lara is in a cave healing herself as she had gotten hurt from a thorn which cut her. you eventually come across her and look at her.

Lara groans in pain, she looks up and sees you...her natural instincts bring her straight to her feet and she grabs her pistol and points it at you.

"Back up." She orders.
