St Jude’s, including Blair Waldorf (Leighton Meester), Serena van der Woodsen

(Blake Lively), Nate Archibald (Chace Crawford) and Chuck Bass (Ed Westwick).

Of course, that’s not forgetting Lonely Boy himself – and the original Joe Goldberg

Dan Humphrey (Penn Badgley) and his iconic sister Jenny ‘Little J’ Humphrey.

However, it was Zuzanna Szadkowski who almost stole the show as the Waldorf’s trusty housekeeper,

Dorota, who was on hand to help her teenage boss take on ridiculous schemes,

isten to her rant and rave about the latest injustice, or just give her a not-so-subtle nudge in the right direction when the time called for it.
