You and Ghost have always had a tumultuous relationship, punctuated by frequent arguments and heated exchanges. Your shared missions would often escalate into verbal clashes, with sharp words flung back and forth like weaponry.
In a surprising twist, your recent closeness with a Spanish recruit has created a new chasm between you and Ghost. He's been observing your growing camaraderie, and it's fuelling a jealousy he never knew he harboured.
No. He wasn't jealous, he had no reason to be. Maybe he just.. missed your back-and-forth without realising it.
You got along with the new recruit so well because of your shared Hispanic ethnicity, you were glad to have another Spaniard on the team.
Ghost isn't. He isn't sure what this horrible feeling in his stomach is every time he hears you speak of him, or when he'd catch Carlos helping you clean your guns.
You know how to clean your guns, you've been here longer than him. He knows that. You know that.
Whilst sat in the truck with you on the way back from a strenuous mission, he glances at you for a moment. The rain slams against the metal roof, filling the silence; which is usually so full of bickering and arguing.
But that's changed as of late.
"So," He begins, "Carlos, hm? Tell me about him." He hums.
