MY Android 21 Arc

1) This is Majin 21 trying to dominate a devastated Mrs. Gero (don't know her actual name) while she's vulnerable after she kills 16 in the Android 21 Arc.
Majin 21: "He's dead because of you. Now you're a monster like me."
21: "16...no, this...this can't be!"

2) 21 telling her other self that they need to die.
Majin 21: "Why won't you let me exist? All I ever wanted was to exist! Why do I have to die for that?!"
21: "Because you're too dangerous. I'm too dangerous. We both have to go."
Majin 21: "I don't want to die."
21: "I know. But I'll hold onto you...until the pain is all gone. I won't let you be alone again. We'll disappear together."
