This theory explains the the real reason why Amy has a crush on Sonic and cares for Dr. Robotnik's robots. Amy always cares for Dr. Robotnik's robots when she feels like Dr. Robotnik is mistreating them in Sonic boom. That's because Amy secretly works for Dr. Robotnik. Also, the real reason why Amy tries to get Sonic to like her is because Dr. Robotnik had possibly demanded her to kill Sonic, so she pretends to like her, just to try to kill him. Amy can often show her aggressive side as a possible sign to try to kill Sonic. So Amy is secretly a villain that works with Dr. Robotnik and tries to use Sonic just to kill him.
