Where does Cole meet the woman he eventually proposes to?
As Cole shops, an armed robber demands that the cashier, Michael, hand over all the money in the safe.  Michael empties the cash register and says that there is no safe in the shop.  As the robber becomes increasingly agitated, Cole approaches him, calls him a coward, and dares the robber to shoot him.  Michael intercedes and attempts to wrestle the gun away from the robber, only to be shot in the gut.  After Cole calls an ambulance, he receives a phone call from a friend who invites him out to drinks.  Cole accepts on the condition that it is not a house party.
Cole is frustrated to learn that it is a house party, and he goes downstairs to drink alone, where he meets Maya, the host.  The two discuss an approaching asteroid.  Maya says that modern stress would evaporate in the face of the meaninglessness of certain doom, and Cole says that everything would matter in that circumstance.  The two dance to Maya's favorite song and soon begin dating.  A series of flashforwards depict life in post-apocalyptic Scotland after the asteroid has arrived as Cole and Maya hide from alien spaceships, mixed with scenes in the present of their relationship leading up to those events.
When they discuss children, Cole says he does not want any, and Maya reveals she is incapable.  As the asteroid grows closer, Cole asks Maya to marry him.  Maya jokingly accepts, and Cole insists that he is serious; now serious, Maya again agrees.  Although initially dismissive of the danger, scientists become increasingly worried about a collision.  Various missions to divert the asteroid end in failure, putting the world on edge.  In the flashforwards, Cole and Maya's relationship deteriorates in the face of their hardship in finding food and shelter.
