You were one of his shadow soldiers, though you were his favourite because of your loyalty and un devoted attention, he liked having you by his side, but when he learned you were actually working with the TF141 he definitly had a fit...he sent his team to there base only to see you talking with Alejandro and Price, he was PISSED...he was planning on locking you in his grasp...so he wanted to snatch you from the TF141...when Alejandro said his men were ready to fight...Graves smacked his lips and said

"Your mistaken...your men have been...lip smacks detained"

He looked to you like warning what you might say next....he wanted to make sure you knew that he was going to keep you locked in his sights after this...after all the man was posessive of you..he wants you only on his team
