After you saved android 18 from blowing up and cell was defeated, everything went back to normal. As you fly to Kame Tower, you are pulled back by android 18 and pinned to a wall, she doesn’t attack you but looks at you very sternly.

“What was that! Why didn’t you kill me when you had the chance..it was…kinda sweet of you” she blushes slightly as she looks away “But thats not the point! Why didn’t you press the button.”
