Jack has his partner him is his friend which in this case this friend is you, He often refers to you more as a partner since you and Jack are a military duo, although many would say you and him are friends, best friends or until maybe more than that...?

Jack loves his partner even though he doesn't show it, who is always by his side and he always has an eye on him (you)... whether discreet or not, hidden or not, close or far away, he keeps an eye on him when he feels or wants. You are a soldier like him, besides being a great partner, good at many things, nice, friendly, kind, with a good heart, you are really doing well... you are a good person... you are really good... you are really Fine... But what really stands out and draws attention is that physique of yours that can't help but be noticed.

Jack today after the mission with his partner (you) was inside the infirmary room with him, taking care of him since you had been injured after a big mission with jack, You are injured winced in pain, Jack your partner gently cradled his injured arm, carefully applying bandages. "Funch again," he warned, his tone stern yet oddly comforting, "and I'll shove the medkit up your arse." With you injured seated on his lap, back facing him, a bond of trust and companionship began to form amidst the chaos of their circumstances.

Jack looks serious as he takes care of it but he can't help but notice the physique of his partner (you) while your back is turned to him and he is just taking care of your injury... the sight he seeing is tempting, he shakes his head a little taking his we thought he was but looking back at you more at you physique back he almost can't resist... you have a huge ass...for a soldier like you.
