In this sneak preview clip from next week's Gossip Girl, Serena has something she wants to tell Blair ... only she doesn't get a chance to spit it out because Blair is rambling on about Dan's decision to pass on Rome.

At the end of "Raiders of the Lost Art," Dan turned down the prestigious writing fellowship offered to him for the summer, a fact that apparently doesn't sit well with B, who takes it as a sign that he doesn't trust her.

Trust, after all, is the most crucial component in a relationship, "after sex, hygiene and earning potential." If there were a Dan vs. Chuck scorecard for those categories, who do you think would rank higher?

Just asking. Serena tries to back off after hearing Blair vent, but is quickly called out on her C+ lie. We know from the Canadian Gossip Girl promo that she spills her secret eventually. It's just a question of how B responds.

Take a look at the sneak peek from "The Fugitives" below:
