* AffectionateNickname: Her dad calls her Bun; her friends call her Carma.
%%* DisappearedDad
%%* TheFashionista
* FourTemperamentEnsemble: Choleric

* ThereAreNoCoincidences: In the books Carmen states that she sees signs everywhere and in book and film both believed the Pants were brought to them by fate.

%%* AttractivenessIsolation
%%* DefrostingIceQueen
* DatingWhatDaddyHates: Downplayed in the fourth book, as while Lena thinks that her father wouldn't approve of her relationship with Leo, she also admits that he'd probably be upset about any boyfriend she had, and she doesn't date Leo long enough to introduce him to her family in the first place.
* FoolishSiblingResponsibleSibling: The Responsible to Effie's Foolish.
* FourTemperamentEnsemble: Phlegmatic.
* ImmigrantParents: Her parents both hail from Greece.

%%* DeadpanSnarker
* EeriePaleSkinnedBrunette: Although more punk than eerie.

* FourTemperamentEnsemble: Melancholic.
* HippieParents: Before they settled down and focused on their careers and new kids, Tibby was raised by these.
%%* SugarAndIcePersonality
%%* TheSnarkKnight

%%* EveryoneLovesBlondes
* FourTemperamentEnsemble: Sanguine
%%* GenkiGirl
* HeroicBSOD: The ''entire year'' between the first and second book serves as one for Bridget.
* TheLadette: Downplayed. Brigitte forgot to pack clothes that didn't make her look like a boy, is very into soccer, is competitive, grew up with in a mostly-male home for quite awhile, but has 4 best friends who are female, flirted "outrageously" with Eric at camp, and isn't above using her looks to attract men.

Carmen likely would have been upset about her dad getting remarried either way, but Albert withholding the information until a couple of months before the wedding doesn't earn him very many points.

* ButNotTooForeign: In the books, it's stated multiple times that his mother is Mexican, and his heritage seems to mean a lot to him. But having an Anglophone surname – and being portrayed in the movies by Mike Vogel, who is white and of European descent – his heritage is easily tossed aside.
