CBS series NCIS really hit hard in 2015 with major shocks in the storylines, which led to some of the best work the cast has ever done. Plus, there were some shocks outside of the show for a few actors too, but they're definitely not of the good variety. 

'NCIS' Star Emily Wickersham Is Vacationing Where Lots Of Palm Trees Grow!

Keeping this in mind, we compiled these most shocking moments since it's the end of the year and we like reflecting.

We will keep this as short as possible so take a look below!

Will Abby Have To 'Break' Luca On 'NCIS' & 'NCIS: New Orleans' Crossover?

Jake Cheating On Bishop
Ugh! They seemed like a near-perfect couple: Jake Malloy (Jamie Bamber) and Eleanor "Ellie" Bishop (Emily Wickersham), but Jake ruined it by cheating on her with another NSA employee.

Bishop Wants A Divorce
Things escalated quickly from Bishop feeling extremely hurt (and rightfully so) to her wanting her marriage to be over.

DiNozzo Gets A Blast From The Past With Jeanne Benoit
In Season 13, Tony DiNozzo (Michael Weatherly) rehashed his past a little with former flame Benoit (Scottie Thompson) as she worked with the team to recover her husband and another doctor overseas in a war zone.



Gibbs Survived That Season 12 Finale
This obviously has to be on our list since so many people were under the impression that Gibbs (Mark Harmon) would in fact be killed off. Harmon would just go about producing for NCIS as well as its Crescent City counterpart then.

Pauley Perrette Got Attacked By A Homeless Man
This would be a shocking moment that is absolutely frightening and not good! It happened in November and luckily the Abby portrayer is doing okay, but it's still so insane that something like that happened to her.

She even gave an update days after it all went down.

Plus, some good did come out of the horrendous situation: She knows only "right now" has importance so she has plans for a new tattoo to be a constant reminder of that notion.

Michael Weatherly Spent Time In Jail & Might Need To Go To Rehab
This is another one of those moments that's not good. Weatherly was driving under the influence last month and wound up in jail for several hours, but could land there longer depending on how his court hearing goes. Apparently his friends and family want him to enter rehab to not only kick his drinking habit, but to reduce the chance of more jail time.

Are there any shocking NCIS moments we missed through the storylines or in regard to the cast members from this year? Tell us in the comments.
