Meeting the Spy new member of the team

When the team has to take cover for a mission and Soap takes them to a safe house, not knowing the spy they need to meet is already in there. Ghost was quiet and pissed off. They had to wait. Soap sees his younger sister and hugs her tightly, and they talk for a while before she heads out in a sexy black dress. My idea takes place in the future where there are Aplhas and Omegas, and due to this, the Omegas go into heat and have to take shots to keep their levels in check so they don't attract unwanted Aplhas. Yes, of course, Ghost and Soap are Aplhas but Neon, aka Aurora, is an Omega, and she took her shot, but Ghost could still smell her and stayed outside so he could control himself
