Just watched Terminator Dark Fate (FINALLY!) but why does Grace take off her shirt before getting into the truck bed to throw giant rebars at the Rev9? Not that I’m complaining, because the view is excellent, but it’s also an odd decision.

Nice! Did you like it? 

Maybe she didn’t want anything dragging at her, the way you fold up your sleeves when you start something? Nothing to get caught or distract her. And she does know she’s prone to overheating, once she starts using her enhancements.
