Yes, Break Girl meets Magnet Girl as her awkward prisoner.

The reverberating footsteps drew closer, and, finally, the Robot Mistress emerged from the darkened doorway. Of course, Break Girl had already met her a moment earlier, even if Magnet Girl didn't realize it, so her appearance was the same and was no surprise.

The showered scientist had been approaching with her head tilted up. She didn't laugh, but one of her thin eyebrows peaked as she saw the sorry state of her visitor. She waved her hand at the Mag-Fly on her prisoner's head to get it to leave, releasing the magnetic hold on Break Girl's brain, but keeping her firmly between the grip of the wall magnets. "Break Girl... What brings the Doctor's specialized assassin to my laboratory at this time of night?"

Break Girl looked at her in stunned silence, although she'd regained the ability to speak.

Magnet Girl continued with her piercing gaze trained on Break Girl's face. "I'll admit my schedule tends to be packed, but come now. I'm sure you have some excuse. Let's hear it."

"Hold on, hold on... Are you trying to act like none of that just happened?" Somehow, Break Girl was more offended by that than the debilitating trap she was caught in.

Her captor's eyes widened only momentarily before setting back to their even keel. "Are you suffering some sort of delusion? Well, your processor was scrambled by a high-power magnet just moments earlier. It's no surprise if you suffered some unpredictable hallucinations while under its influence. Now, tell me why you're here.... Or, if you don't want to, you could help me test these magnets? They were created to capture that sister unit of yours, that Buster Girl. In that sense, you're actually the perfect subject to demonstrate their potential, Break Girl."

Break Girl gulped. She ought to focus on a good excuse, but... "Seriously?! Am I supposed to let Grabby Girl over there get away with that? I wanna give her a piece of my mind!"
