with no romantic partner most of the time to appease. This can be attributed to the fact that he has slept in the master bedroom in the company of several women who no longer are a part of his life, stirring up bad memories. The bedroom now serves as a store of his keepsakes and an extra place for those he considers special guests to sleep. This changes in the season 13 episode "Scope" when Gibbs starts sleeping in his bedroom again, slowly letting go his bad memories. He does not tolerate submissiveness. When someone on his team allows another person to manipulate them, Gibbs takes it personally as an affront to his work ethic. Gibbs is unapologetic by nature as well, as he considers apologizing to be a sign of weakness when it is done fearfully in light of intimidation, and suggests to his team members that they should refrain from doing so; a sincere apology given when someone is distraught or has meaningful reasons to apologize is acceptable.

This left his mother-in-law in so much grief that it led to the dissolution of her own marriage. Eventually, he found peace with most of his regrets in the 200th episode of the series "Life Before His Eyes", where Gibbs learned that even if he had been present in their lives and thus prevented the sequence of events that ended in their deaths from ever coming to be, the path his life would have taken would have instead led to his own demise.

In season 15, he appears to be alternating in-between both these looks; wearing a dress shirt on some days and polo shirts on other days. Gibbs also is noted for
