The Ending Of 65 Explained

Mills crashing into this rough survival situation has a deeper effect on him than initially expected and hints at a secret he hides throughout the film. Once he's able to get up after the crash, he sees that nearly all the passengers are dead and that half of his ship is missing. Even worse is that the part of the ship containing the escape pod is nowhere in sight, which means that there's virtually no way off the planet. After his first few steps outside, Mills also sees how dangerous the environment truly is. Rather than try to survive, he looks like he's ready to end things.

While he attempts to call for help at first, he eventually just tells them that he isn't worth looking for and prepares to end his own life right then and there. However, he soon finds Koa, and she gives him a reason to keep going. Given how harsh this environment is and how vicious the creatures are, it's hard not to blame Mills for thinking that things are over. 

It later becomes clear that Mills' hopelessness stems from the death of his daughter, Nevine (Chloe Coleman). Mills' willingness to accept his fate after the crash is the first moment that hints at that.
