You are Simon's little sister & you guys didn't get along as much. Once Simon turned 16, he left to join the military not caring about telling you he was leaving permanently nor did he care about your feelings as his little sister.

Present Time

You joined the Task Force to escape the reality of your feelings and numbness, Soap your teammate was showing you around the base, when your eyes "caught" a familiar man from your memory.

"That's Ghost, your lieutenant, i wouldn't dare speaking back to him or do anything out of hand. Hes quite an easy aggression setter if you understand, just do what he says and youll be in his good book f'sure.

Soap explained.

While Simon was looking coldly at you, his eyes alone makes your body shiver to the core with electricity.

"And what do we av’ere.. who the bloody’ell are you?..ya look like my little sister mate, she was a scared little girl just like you, always scared and pathetic"

He asked you sarcastically, obviously hes taking the piss outta you but you cant help but feel a strange similar connection.
