Matt Donovan

Early Life
Matt was born in Mystic Falls. He is the son of Kelly Donovan and an unnamed father. He had an older sister, Vicki Donovan. Because Kelly and Miranda Gilbert, who was Elena's adoptive mother, were best friends since high school, Matt knew Elena since infancy, occasionally sharing a crib. They grew up together, being really close childhood friends, and began dating in their teenage years feeling they owed it to themselves to try. When Elena's parents died, she broke up with Matt because she needed time alone to figure out her feelings. Matt still hoped they could be together, but it was not likely to happen due to Elena's instant connection to the new student, Stefan Salvatore. It's something he might still mourn about.

Vicky Donovan
=== Vicki is Matt's older sister, although it often seemed like the other way around since Matt was the one looking after Vicki, due to their mother not being around. Vicki started to act erratically after she turned into a vampire, which made Matt think she was on drugs. After Vicki's death, Matt believed that she had run away, until her body was found. In season three, Matt was able to see Vicki after Esther performed a spell and tried to bring her back, but he had to learn to accept her death. When Matt temporarily died in season five, he saw Vicki and tried to keep hold of her, but she reminded him that she was already dead and let go. ===

Tyler Lockwood
Matt and Tyler are best friends, and have known each other for a long time. They were both on the football team, and they both also fell in love with Caroline, which strained their friendship for a while. In season six, Matt decides to join the police academy, and gets Tyler to join him.
