YMMV / Batman Beyond S 2 E 26 Untouchable

• Informed Wrongness: Dana is portrayed as an unreasonably jealous bitch over Terry's interest in Irene. However, Terry explicitly admits to Bruce that he's enjoying Irene's possibly romantic attention and deliberately hiding the fact that he has a girlfriend from her. In other words, Dana's jealousy is entirely correct.
• Unintentionally Unsympathetic: Irene's portrayed as an innocent, naive girl who doesn't realize that her new male friend has a girlfriend. But the end of the episode shows that she had a boyfriend that she didn't tell Terry about. So she was also leading him on.
