Where We Left Off: After Beckett didn't tell Castle about receiving a job offer in Washington D.C., she and Castle wrestled with where their relationship is headed. But before Beckett could decide whether she wanted the job, Castle stunned Beckett — and viewers — by proposing!
What's Next: The show won't waste any time revealing Beckett's answer — both to the proposal and the job offer. But that's just where the drama begins. "There are four possible outcomes, and each of them have their own particular consequences," creator Andrew W. Marlowe says. "There's no version of this that's easy and that they live happily ever after — even with the good stuff." House's Lisa Edelstein will recur as a federal agent who influences Beckett through her tough next steps. "How can she make any choice without giving something up?" Marlowe says. "She'll have to sacrifice something."
