How do we know she knows how it works? She needed Paul to boot it back up when it got knocked out and she did need him to turn off the limiter. A choice was made by the creative team to have him in control over the tech he gave her. Maybe that was just to give him something to do, maybe it was to reinforce their "partnership" or whatever, but it's there on the page. It doesn't matter if he listened to her order or not, she still needed for him to. She clearly didn't have the ability to do it herself. That's problematic.
Yeah, actually. Bruce definitely held the power in that relationship at that time. He literally robbed Terry of his power at the press of a button because he could. He made the suit and it relied on Bruce to keep it up, like Paul making and tweaking Jackpot's gauntlet. It's not that he never had agency, it's that it was taken from him in that moment.
