Ophelia watched Tracey quietly for a few moments before moving slightly closer. Her hand rested on Tracey's cloth-covered arm, careful to not contact skin to skin. She wanted to be comforting in the way she could manage. Tracey was important to her, no mistake could be made about that. She was thinking. This happened quietly, without much obvious action, but it was there. She could do this. They both could.
"Yes. A potion. And some papers." Make it seem like the man had left after everything happening in the wizarding world maybe. It wouldn't be hard and using Tracey for this, while it would be hard for the other girl, would be the best way. It would have to be followed with a memory wipe. She knew that, though she would not bring it up now. It would be done when it had to be. That was all there was to it. She could find one of the things she'd already brewed. They could do this. Soon. Maybe the best time would be the next day. It was obvious they were together now and that wasn't something that was typically a one day thing. She could side along apparate Tracey from her home. They could floo there. Things were coming together. Her eyes went to the shop owner with a small smile. "This, please." She held up the dagger. The money could be pulled directly from her family's vault. There was no worry there.
"We need to go to my home." Because things to get this done could be obtained there. After that, they would start the rest of the process. It had to be done and fast, while the ideas were fresh. Better to get the first step now. Her father and brother gone and her mom planning to move. After that it would all be simple.
"No explosions. Trust you both." Which was saying a lot for Lia. "Gloves." Because even with that trust? It would be easier for Ben to hold her and Tracey to stab her if she wasn't trapped in a vision from one or both of them. It didn't always happen but skin to skin contact was always risky for that reason and so it was easier to just avoid it.
