I'm just as shocked as you are, but hey, who wouldn't be me without a few Heartwarming Moments that I'm about to give you?
In Emperor Joker, sweet darling Harley Quinn was questioning me whether I was gonna do away with her too in my bid at reality destruction. I assured her that I would NEVER harm her, and, for her many "tears of service", I gave her the best seat in the house to watch the show by turning her into a constellation.
Then I looked up and smiled (a nice smile, just not my usual smile), and I said, "Always wanted to see my dame in lights." Repeat after me: Freakin' awwwwwww!
