Mari

Mari is a little girl who got lost in the woods while collecting rare orchids with her mother, prior to the day when Lara, Sam, Jonah and Kaz reach their town. Lara is approached by Mari's mother telling her that she got lost. Later Lara accidentally stumbles upon the place where Mari was trapped and both of them leave the cave through the waters, where they were forced to fight an alligator. They rest near a tree for the night and on the next day, Mari scribbles her a map of where Grim was held captive. She parts ways with Lara with a warning for Lara to "be careful" and "not to do anything silly".

Personality
Mari is shown as a smart and savvy kid who has a knack for exploration and survival, which is evident in when Lara asked her how did she survive in the cave and with Mari answering that she "ate moss and drank from the water, which was clean". Mari is also very brave as she helped Lara fight an alligator of, but asking why she killed it later on - that implying that she has a moral code forming in her mind.

Trivia

 * Lara has shown quite a liking to the little girl, going as far as saying that if she ever has children she wants them to be like Mari.
