Several long hours have passed since Gibbs has returned to dry land and he can't believe that they'd been extremely lucky. He and Kate had managed to successfully stop an eco-terrorist, Sean Travis who had been posing as a murder victim, Petty Officer Drew from releasing sarin gas into the USS Philadelphia's air conditioning system, an attack that would have caused the loss of many innocent Naval and Petty Officers on board the submarine.
An attack that would have also caused a huge wave of embarrassment for both the United States Navy and NCIS.
Gibbs also knows too well that they got lucky today and that if the attack had worked, then there's also the likely chance that their bodies would have been eventually found, maybe days, weeks, months or even years after the tragedy or maybe, maybe not at all.
Thankfully, Gibbs had caught onto the scheme and after realizing that Travis had bobby-trapped himself with the container, having committed suicide as a back-up plan while knowing full well that his body would be placed inside a freezer which would cause the gas to leak, they'd managed to send Travis's remains out of the sub via the torpedo room.
With Travis dead, the FBI are now busy arresting or tracking down the rest of the members of the radical eco-terrorist group that Travis had been a part of but while the day has been a success and the case has been solved, Gibbs hasn't been able to stop thinking about Norfolk Naval Base NCIS Special Agent Timothy McGee, the same person who called in Gibbs and his team to help investigate the dissolved body in the barrel of acid which had ultimately led them to the terrorist attack.
From first impressions, Gibbs knows for a fact that McGee's like all the younger Agents who have come before him: young, green, very, very eager to please his superiors and more than willing to stay in the background in the hope that no-one will notice him.
Unfortunately, and much to Gibbs's own private anger and annoyance and Kate Todd's own disgust, Gibbs's senior agent and second-in-command, Anthony DiNozzo, seeing an opporunity just to prove how experienced he was had used McGee's shyness to his advantage, bullying the younger Agent into helping him as well as pulling an all-nighter by staying at the crime.
While in his leader mode, DiNozzo had unsurprisingly even insisted that McGee call him "sir", something that Gibbs hates but DiNozzo seems to live. Gibbs also knows although McGee's appearance was brief and that McGee was left fearful of him after their first meeting, he's left a lasting impression on Gibbs who only hopes that he hasn't seen the last of the innocent and very handsome Norfolk Agent.
Because believe it or not, Leroy Jethro Gibbs is actually more than willing to admit that he has a crush on Timothy McGee.
