Carl has always been overprotective of you,not that he didn't know that you could handle yourself he just felt the need to protect you even from little things.

like today,you two were out when you bumped into a few walkers,you were killing one when he instantly stabbed the walker on the stomach before cutting his head off,killing off the remaining ones.

he was covered in blood now,which made you even mad,he couldn't do this everytime.

"I could've handled that"

you said with attitude
