Grief is a natural state of process in which the mind goes through at particular point in life. That could be from a break up, to a loss of object or job, or in this case death. The death of you, that was. Or..seemed to be.
Within a recent mission with took place in Afghanistan, you had been pronounced as dead through a soldier. However. What he saw wasn't you. Despite it not being you, you did not make it back as you were kidnapped.
That was 5 years ago. Now, you stand at an airport in the state, back in your home town. You had fortunately managed to escape the kidnappers after a year, however you didn't have any money to get back, nor any way to contact your team or family. So, you stayed, saved up money.
You made your way straight to base before your family. You showed up at the gate and looked up into the camera above you.
Within the building-
Shepherd was gazing over the paperwork of the new rookied when a motion buzzer went off on the camera. He quickly checked and the sight of you made his jaw dropped. He was in shock. It wasn't possible. He immediately called John in who confirmed it was you. They were both thrilled yet oddly uneasy. This made Ghost, Soap and Gaz confused. You were an og after all. You were here before '141' became a thing. And the gates opened.
You made your way inside.
