JACKSON: I think we should get married … Soon.
SOOKIE: Are you pregnant?
JACKSON: What do you say? Sookie?
SOOKIE: Yes! I say yes. Oh my God, we’re getting married!
In typical Gilmore Girls fashion, a marriage proposal comes out of a fight, and the wedding is scheduled to happen as soon as possible.
Sookie seems to have packed the basket expecting or hoping for a proposal, because there’s a vase of roses, candles, champagne, and even what looks like a tiny wedding cake with white icing. She may not have been quite so surprised by the proposal as she acts. Is it possible that Sookie deliberately ignored Jackson’s hints about moving in together because she was holding out for marriage?
