Everyone is born with a timer on their wrist that counts down to when they meet their soulmate. Clarke has never had a timer and is destined to be alone as she watches everyone around her meet theirs.
"How long do you have left?"
Upon your wrist is a clock. Started at birth, and counting until the day you and your partner meet. Choosing to pay attention towards it is each person's own decision. Would you?
