Even though it's rather immature, Barbara's, "I'll call your mom" thing reminded me of one of the main reasons I really don't like Steph. Basically I can't believe how utterly horrible Spoiler has been to her mom. I remember people posting scans from Robin when she showed up again and I was all like, "Oh, she's back. I don't like her, but everyone else seems to, so that's cool for them." And then I got to some scans where Tim was mad at her about the whole faking her death thing and then we found out that she hadn't told HER OWN MOTHER that she was alive and back in Gotham. Even worse, if I remember correctly, Tim had to MAKE HER go to the hospital to see her mom. I can't even imagine doing something that cruel to any of my family. And you could make the argument that she didn't tell her that she was in Africa because she wanted to protect her in case someone suspected she was alive, but there is no excuse to not tell her when she is back in Gotham, active in costume again, and using her real name. That whole thing just made me really think that Stephanie is extremely selfish and doesn't think much about those who care about her.
So really, I wish Babs WOULD call her mom. Stephanie's mother (who I am assuming doesn't know that she's Batgirl) deserves to know that her daughter is once again doing something that could lead to her being killed/nearly being killed again.
