Killer Frost makes her right arm to look like a sword-like spike and Grant comes between and Killer Frost starts to look at Grant and he starts to laugh.
 * Grant: Joe, we must turn good.
 * Joe: What? Why?
 * Grant: Dad had turned good as well.
 * Joe: So?
 * Grant: Do you want to hurt his feelings?
 * Joe: I guess not.
 * Grant: I wanted to cut off Oliver's left arm.
 * Killer Frost: Well time to grow up. I was supposed to destroy Cisco's arms. But I showned mercy.
 * Joe: But mercy is for the weak.
 * Grant: He did not mean it. He is making a joke. Why on earth would anyone say such a depressing thing?
 * Killer Frost: He does not laugh.
 * Grant: He can't laugh, he is having mental issues. But he is laughing from the inside.
 * Killer Frost: I guess.

As her right arm returns to normal.
