Matt Donovan (Zach Roerig), plays a supporting role in "The Vampire Diaries". Matt is first introduced in the show as the former boyfriend of main character Elena Gilbert (Nina Dobrev). He is also the brother of Vicki Donovan (Kayla Ewell). Through the series, he tries to get over his relationship with Elena, and develop new relationships with other characters on the series.
Matt did not have the most fortunate of upbringings. His father appears to have been absent for most of his life, and his mother, Kelly Donovan (Melinda Clarke) often abandons her family for extended periods of time, and struggles with alcohol abuse.
Initially, Matt still showed signs of still being in love with Elena. Much to his dismay, Elena becomes romantically involved with another boy, Stefan Salvatore (Paul Wesley) who is also a vampire. This severs any chance for Matt and Elena to rekindle their relationship. In later episodes, he begins to date resident "Queen Bee", Caroline Forbes (Candice Accola).
Through the show, Matt develops from a relatively minor care-free character into a deeper, more conscientious role. To support himself, he works at the popular local hangout, Mystic Grill. He is shown to care very deeply about his sister, Vicki Donovan; and is at her side when she is left in a hospital bed as a result of a vampire attack by Damon Salvatore (Ian Somerhalder). Matt also tries to convince his mother, Kelly, to lead a more stable, family centered life.
Matt Donovan is a popular character on "The Vampire Diaries", not only due to his good-looks, but because he has the type of personality and values that appeal to teenage girls.
"I want you out of the house, and my life, by morning."
"Turns out Vicki is just like our mother. I can't count on either of them."
"Don't say anything. You're a dick. End of story."
