S2·E21 Wedding In Black

A mysterious snowglobe is mailed to Curious Goods. When Micki gives it a shake, an old boyfriend of hers shows up, and convinces her to join him at a bed & breakfast. Then Jack and Ryan are both visited by old friends when they shake the globe. It turns out that each of the three newcomers is working for Satan. If Micki can be tricked into sleeping with her boyfriend, then she will be considered wedded to Satan as she ""willingly"" did so. Jack and Ryan, lured to the hotel, are separated from her, able to witness what is going on but unable to contact Micki. It turns out they are trapped in the hotel within the snow globe. Ultimately, Ryan's ex-girlfriend helps them, and they manage to drive a car into the edge of the globe, knocking it off the shelf it is resting and shattering it (and freeing themselves) before Micki can consummate her wedding with the Devil.
