Next week's episode of Cupid is being bumped for The Unusuals, which will air twice next week. The simple rundown:
The episode of The Unusuals originally scheduled for April 22 at 10pm, moves to April 21 at 10pm. The episode of The Unusuals that was supposed to air on April 29, will now air on April 22. The episiode of Cupid originally scheduled to air on April 21, will air on April 28.
It's hard to know exactly what to make of this, but the simplest tea leaf reading suggests they want to try to give The Unsuals a little more exposure right now at the expense of Cupid.
