Pinkie neatly folded the map Twilight had been using, and slipped it into the edge of her tight-fitting black pants. Then she pulled out the one she'd bought, opened it, and set it down on top of the table where the old one had been. She placed Twilight's tools on top of it, and stepped back. Hands on her hips, she watched the work she'd done. One hand moved to her chin, and she stepped back towards the map to move the pencil and ruler to a different position. "There. That's better, don't you agree?"
Twilight, of course, didn't answer the question. She couldn't, right then. Pinkie wasn't actually sure if she could even hear it, though she didn't particularly worry about details like that. It wouldn't have mattered anyway, every bit of memory would be wiped out.
Pinkie looked at the clock up on the wall. She hadn't taken too long going to buy the map and coming back. Not yet, at least, so long as she finished everything quickly enough. She tapped her forehead with a long black nail, wondering if there was anything else she was missing. With her other hand she grabbed the coffee mug Twilight had brought with her before sitting down to work on the map, and downed it all in a single sip. It was cold. Like her soul, she thought, but only to keep to her character. She'd explicitly been told, actually, that there was no need for her to stick to that character and aesthetic. But she wanted to.
She set the mug back down, on top of the map this time, then turned to Twilight. "I really am sorry about this whole thing. But we have to. Trust me, I wouldn't be doing this if I wasn't sure it's the right thing to do and if you know me then you know it." She walked towards the girl, who was lying limp against a sufficiently large piece of machinery, kept upright by two glowing black and purple crystal formations wrapped below her shoulders and around her torso.
Pinkie took hold of Twilight, whose eyes were glazed over with the same black and purple as the crystals. The crystals themselves disappeared as Twilight slid into Pinkie's arm. "There we go," Pinkie said, beginning to carry Twilight towards the chair. "In a couple minutes you'll wake up, and everything will be fine. It'll just feel like you fell asleep. I'm sorry about wasting your time like this, but we don't have an alternative if you find the location of that portal. Please run into another one next time."
Gently she slid Twilight into the chair, and placed her leaning over the map, head and arms atop it like she'd fallen asleep there. She gave the girl and affectionate pat on the back. "I'm doing this for everyone's sake. Yours and the girls' and everyone else's." There was hesitation on Pinkie's face for a moment. "I hope I'm doing the right thing," she whispered. Then she stepped away from Twilight, and disappeared in a shadowy corner of the laboratory.
