Warning! Spoiler ahead for NCIS: Origins episode 3.NCIS: Origins has created a Jackson Gibbs plot hole before it can even explain his questionable involvement. Jackson, played by Robert Taylor, is one of several pre-existing NCIS characters to appear in the spinoff. He appears in a supportive role, as he tries to help his son, Austin Stowell’s Leroy Jethro Gibbs, heal following the death of his wife and daughter. As NCIS established, it is clear that Jackson and Gibbs have a weak relationship, but NCIS also said that the characters had no relationship at all, which is not true in the prequel.
