Deena DID have the same drive as Curtis and started to morph into him which is shown when she agrees to ex out Effie's existence in the history of the Dreamettes. I think the booboo really started to stink when he refused to have a child with her. Just imagine, ya own husband not wanting to have a kid with you. Although that song was not originally in the stageplay it made so much sense in story and gave Deena something she honestly never had...her own voice.
I'm really proud that Beyonce did play this role. It really shows different sides of her, that despite the bs in DC and her overbearing father who in everyway resembles Curtis character, the overthetop Diva stuff...she can take a seat without falling off or fallin out.
