Placing the dagger in Pansy's hand, Alecto nodded. "Wherever you wish. The forearm is the most common," Alecto motioned towards her own arm, before whipping out her wand. "however, it's not required to be there. Wherever you can conceal the wound until it heals up properly would be suitable."
This was all moving a bit fast, but to be quite honest, Alecto didn't have much time. There was so much more that needed to be done before the day was over. Pansy's oath took top priority, but now that it was almost a sealed deal, Alecto had to start thinking about her next destination.
Tapping the wand in the palm of her hand, Alecto waited for Pansy to select a location to draw blood, before the incantations laced her blood to the promise she just made. It wasn't binding, but it was enough to show her alliance to the Death Eaters. Her willingness to inflict pain unto herself was really all Alecto needed, but the oath was an added bonus.
