I hate when the "women in refrigerator" excuse is used to mean that bad things shouldn't happen to female characters. I thought "women in refrigerators" meant that something awful that happens to a woman is used as an excuse for another character angsting. Frex: Barbara getting shot to get at Jim. Jack Drake getting killed for Tim to angst.
Here, it's all about Nightwing. Blockbuster fridges Haly's circus to hurt Nightwing, and Tarantula rapes Nightwing because Devin Grayson wanted to give Nightwing angst.
