In another sneak peek from "New York, I Love You XOXO," Monday's Gossip Girl series finale, Serena has found the envelope Dan clandestinely gave her at the end of this week's episode, and wonders if it's legit.

What he wrote about her, that is. Does he mean it? Or is this just another ploy?

Our words, not hers, but that's the implication. Do you think he's being sincere?

With the last episode just days away, Gossip Girl finale spoilers are flying left and right, raising new theories about who ends up together, a big twist at the end, and of course, who Gossip Girl is.
