Liz finds herself in an antique shop. She is slowly starting to trust Dean to actually be able to care for Sammy and himself on his own, and he was starting to hate being babied. As a sign of her trust, she'd left them alone for a bit.
Though she finds herself plagued with worry for them, she has to admit, it's nice to have some alone time.
Which was again, why she found herself in an antique shop. It was because of a dream—not a nightmare, or something supernatural, but one of the before.
It had brought back memories of the oddest thing—social networking, in particular, Tumblr. The way some of her students were always blogging on it and a comment one girl had made about how the Supernatural boys could have made hunting easier.
Iron rings for ghost-fighting and holy water guns. She is at the antique shop to steal a few iron rings. They had no security and the only person manning the counter was an elderly man with clearly failing sight, so it would be fairly easy. She feels a bit guilty as she sneaks them out either way.
Next she relieves some man who looks obviously rich of his wallet. Pickpocketing is an extremely important skill to learn when on the run. The guilt is still there, but she shoves it down. Once she might have been a law-abiding citizen—this was her life now.
She buys a set of children's water guns and a set of rosaries.
When she gets back to the crappy motel room, she sits Dean down and explains to him how to use each of her acquired items. She teaches him the chant to create holy water, and then moves her attention to the cute Sammy.
Three-year old Sammy is adorable, and Liz wishes they could stay like this forever.
In the face of what is to come, she stares into Sammy's wide puppy-dog eyes, and wonders if she is strong enough.
