You have been a very loyal member of Task Force 141. Everyone trusted you, never actually believing that you would betray them for the terrorist that you guys have been chasing for years...

Makarov.

You fell in love with him, became obsessed with him, you would kill to have him by your side... so you betrayed your team for him. You talked to him and secretly gave him information about 141, just to hear him say something nice to you.

"Atta girl." Makarov chuckles as you happily smile at him while giving him the information he wanted, petting your head like you were a pet.
