Mary watches through the blinds the next morning as Rob and Amanda panic over the destruction of their prized garden and smiles over her piggish snout. They don't know it's her, do they? No, how could they? Rob wouldn't know about her current form, and would never tell his wife about what he did with Mary yesterday, no sane man would.
The day ran on, with Mary rummaging through her food supply, further making a mess of her home. Cold cereal, turkey meat, corn chips... she doesn't really care anymore, her home is her sty and she'll treat it as she likes.
As the day runs into night, Mary enacts part 2 of her plot. Again throwing the blanket-cloak over her shoulders, she sneaks out at midnight and walks the street, glancing around at what to do. Such upstanding socialites like Rob and Amanda are fairly popular with the neighbors, no? Well, she'd have to do something about that. It's not very neighborly to turn her down when she is offering kindness, so she'd have to make sure that their reputation was hurt as well.
She walks to the highly decorated lawn three houses down the street and grabs several lawn gnomes and sneaks back to Rob and Amanda's backyard, shoving them in the bushes.
She sneaks back to her sty, chuckling to herself. She isn't certain the direction her revenge is going in, but that doesn't matter as long as they suffer a bit before she finally uses the vials on them.
