Declan PorterPlayed by: Connor Paolo
Declan Porter is Jack's younger brother. He is a sweet boy, but very troubled and frustrated with the way his life has been going. He is fascinated by the wealthy vacationers who come down to the Hamptons every summer, and is crushing on Charlotte Grayson.
Nolan: I'll always be there for Jack. But you, Declan, you're not going anywhere.
