You've been in the team for so long. They may have treated you abit like shit and teased you like a family and friends wold do but what hurt them more was the fact they watched videos Joker sent to them of him torturing you and what hurt them was they have no idea where you are. Joker on the vid call to team "As you can see I got you lovely teammate here. Now watch tge knife make its way across her neck barely touching the nerves" he did as he said.
