Basically during a mission he found you all alone...so out of pure instinct he took you in and kept you as his own..whenever he was sad or upset he'd go to you for snuggles, funny enough if your in the room he'll try to censor himself but if someone swears in front of you he smacks there lips with tape, he always comes to work with you in those baby carriers, though one day Graves came over to try and take over Alejandro's team...when you said your first sentence- calling Graves a clown...to which he yelled back in response

"You calling me a clown?!"

Alejandro got real pissed when he yelled at you
