Come out and play (Hank, Eric)
Baba Yaga'd sent a woman dressed in the crone's clothes to the Tower, given the woman instructions, and set her loose. The woman would definitely smell like the crone as she stood waiting for the beast to come out and play. She was built much like the crone, or Red, was, and she held a small basket with pieces of tasty meat inside. On the basket was a small envelope, inside, a note:
You may enjoy this one, or you may come play in the park. Bring the food. We could have so much fun, my darling.
It was unsigned, but the scent alone should be enough to tell the blue furred genius who sent him his little present.
The crone sat on a park bench and watched the world move around her. She had picked a spot that seemed more wooded than normal. Quite possibly her cabin was close by. Perhaps Eric would feel the strong hint of mischief, anticipation, and lust from the small woman. She was certainly in the mood for a distraction with so much possibility.
