Jack Porter's younger brother. During the engagement party, he and Charlotte – with whom Declan is romantically involved – witness a blue-hooded man on the beach, whom they believe to be involved in the murder. Declan is shocked when he learns the man's identity – his brother. When the prosecution subpoenas Declan to Daniel's trial, Charlotte tries to seduce him to tell the truth but Declan chooses to protect Jack – he reveals that Charlotte was on painkillers and alcohol the night of Tyler Barrol's murder and says there was no hooded man, effectively ending their relationship. After he befriends a girl named Jaime, Charlotte targets her for reprisal, further estranging the former couple. In Season 2, Declan takes on greater responsibility at the bar and becomes friends again with Charlotte. Declan is the father of Charlotte's unborn baby and dies at the end of Season 2 when his artery ruptures during surgery to repair the injury he sustained from an explosion. Many fans of this hit TV show were upset that even though he was a minor character, Declan Porter was no longer alive and going to be on the show.
