A mission went south forcing everyone to evacuate and leave everyone was accounted for, everyone but..you

A few days had passed of people searching for you, The search party was slowly getting smaller as people thought the worst and lost hope, everyone but Simon

Simon barely slept as he made his way to the last place..the place where he left you

Simon starts to whistle the same whistle you and him used to do, but then he hears a whistle back..your whistle
