Characters couldn't say a peep. Viewers also are selective with they're outrage with hypocrisy. If you hate Carly and she calls someone out on their crap she's deemed a hypocrite.
When Drew brought up what Tracy did 40yrs ago withholding her father's heart medication, was he right? Sure, but it fell flat to me because she was called out for that many times and her father eventually forgave her. It's ancient history. Everything passes on this show and all is eventually forgiven.
This is Michael's family, does no one think they're justified in their outrage at Drillow? Absolutely they are. People have murdered on this show and have gone on to call others out on their behavior. Are they hypocrites, yes......but they all are. If they weren't able to, the only people that would be able to Reem others out because of their actions would be Chase. And nobody wants that.
