Szadkowski says early in the series she felt it was Dorota’s duty to play cheerleader to Blair’s antics, which may be why the character was given a more active role in the series beginning in Season 2.
Zuzanna Szadkowski speaks enthusiastically to Hello Giggles about her character on Gossip Girl, and with good reason, as the actress helped shape Dorota as a character early on in the series, when she wasn’t introduced until later on in the novels.
Though not necessarily a massive part, Dorota was always around to offer advice to Blair, and even do her bidding when necessary.
