" ... Jackson's going to play tomorrow. ... And I prefer my boyfriend" (downward glance) "at peak performance."
Lydia has a focus on the materials and has a very blunt and sexualised sense of humour. She presents herself with a ditzy, self-absorbed appearance so to maintain her relationship with Jackson Whittemore and promote her popularity at school. Lydia can also be exploitive and manipulative with people using them whenever it suits her purposes as she makes out with Scott in spite of her relationship with Jackson and being close to Allison.
" ... Lydia's one of the finest students I've ever had. Her A.P. classes push her G.P.A. above a 5.0. ... socially, she displays outstanding leadership qualities." - a school teacher on Lydia
"A Field's Medal is the one I'll be winning." - Lydia, smiling, to Stiles
In truth, behind her mean girl facade, Lydia actually does care for her friends, being supportive of and understanding of them. She befriends Allison Argent on her first day. She proves to actually care for Jackson to the point she's in love with him, despite Jackson's abhorrent behavior. She also discerns that Scott would do anything to protect Allison. She is initially disdainful and dismissive towards Stiles because of his antics and obsessive behavior towards her. Overtime she becomes best friends with him as they work together. She is also a meta level genius, excelling at reading and her studies in a wide variety of subjects.
"Would someone please tell me what the hell is going on?!" ... Are you real? ... Why me?" - Lydia suffering under Peter
Upon her introduction to Beacon Hills' supernatural side, being attacked bitten, then possessed at the hands of Peter Hale, the subsequent symptoms and psychological torture inflicted upon her, Lydia suffers multiple mental traumas and breakdowns, being massively confused and terror-stricken. Though she was forlorn that her friends were keeping secrets from her, and that she was suffering because of it, she manages to put on a stoic, brave face, as pointed out by Peter, and determinedly pushes forward. Once she comes out the other end, and then recovers with the support of her friends, finally being let in on the supernatural, Lydia matures by overcoming her insecurities, becoming more confident and sensitive.
After coming into the supernatural, Lydia decides to no longer hide her natural strengths and lets go of her superficial concern of others' perception of her. She displays a braver, more selfless side in facing the kanima side of Jackson leading to his being cured, and coming to accept his moving away. Once she adapts to her new world, Lydia demonstrates that she is not afraid to tell people what she thinks of them, firmly telling Aiden, her lover, that he's a killer, a bad guy because of his part in Boyd's murder ignoring his charms though she continues her liaison with him. Similarly she stands up, refuses to back down from people like the malevolent alpha Kali or Gerard Argent. Though she is initially terrified by her strange powers, her being drawn to murder scenes, Lydia eventually makes the decision to stop fighting her abilities, and upon the discovery she is a banshee, she decides to potentially use her powers to do good, to prevent any innocent people from dying. With this benevolent new mindset, she naturally comes into her position as a member of Scott's pack.
