First of all, nice of you not think about Cass as a woman.
Secondly, this story was published before the decision was even made for Steph to become a Robin, which derailed the whole plan they had for the buildip. If you really wish to complain about Bruce's behaviour, pick the GK issue where he told Steph to quit being Spoiler that lead to this issue, where we were shown Bruce's side on the matter.
