Loyal fans of Hawaii Five-0 know all about Terry O'Quinn as retired U.S. Navy Seal Joe White. Recently, he was on "La Po'ino" (Episode 13, Season 5) and "Pono Kaulike" (Episode 18, Season 5). White helped Five-0 track down and stop a deadly virus from being released and helped McGarrett get Danny out of trouble with internal affairs. He's clearly a good friend to have.
