Declan Foster Porter (born March 23, 1994 - November 5, 2012) was Jack Porter's paternal younger half-brother and Charlotte Clarke's boyfriend. Declan constantly encouraged Jack to go after Emily Thorne, and he declined the advances of Amanda Clarke. He and Nolan developed a tight bond, as Nolan protected him and paid for his tuition at Collins Prep (Declan once described him as having "a heart as big as his checkbook"). In the season 2 finale, "Truth, Part 2", Declan died during surgery after being injured in a bombing at Grayson Global. Little after finding out he was going to have a child with Charlotte.
