Grey's Anatomy has been on the air for 17 seasons and 16 years. Over that time there has been no shortage of medical miracles and moments where different characters are given their chance to shine. Main characters like Meredith, Amelia, and Jackson have seasons worth of storylines under their belts, but only one moment can be defined as their most iconic scene.

An iconic scene on Grey's is usually when a character gives a big speech, comes to a shocking realization, or discovers the missing piece to a medical puzzle they've encountered. The best part of these iconic moments is that no two are the same, and each explains what makes the characters on the show the way that they are and why they behave and approach life the way that they do.

Jackson Confessing His Love For April

Season 10 of the hit medical drama saw trauma surgeon April Kepner preparing to walk down the aisle to her paramedic fiancé Matthew, much to the dismay of Jackson and Japril fans.

In Jackson Avery's most iconic scene, he stood up and objected to the legal union of Matthew and April, declaring his love for the latter and asking her to run away with him. His speech included him saying, "Even the things I don't like about you, I love." His plea worked, and the two ran off and eloped.

Amelia Discovering Her Own Tumor

Amelia Shepherd followed in her big brother's footsteps as an excellent neurosurgeon and respectable doctor.

That's why her most iconic scene was in Season 14, where she looked at an MRI scan of a massive brain tumor, only to discover that it is her own. It's ironic given her job in neurology, and heartbreaking as she realizes that she is sick and will have to have brain surgery instead of performing it.

Mark Sloan had plenty of great moments through the years, from becoming a father to Sofia to repeatedly fighting to win Lexie back, he was nothing short of iconic every time he graced the screen.

However, his best moment came right before his tragic death, where he had one last chat with his mentee, Jackson Avery, in which he offered him some words of advice. While speaking from experience of not getting back with Lexie before his death he urges Jackson to tell the ones he loves how much he cares for them saying, "If you love someone, tell them." And that's exactly what Jackson does to April a season and a half later.

George O'Malley was known for his more awkward moments, like being the first intern to perform surgery and having to operate on a patient while trapped in an elevator.

However, his most iconic scene was in Season 2 during the episode where a patient has a bomb in their chest. George is taking care of Miranda Bailey as she prepares to give birth to her son. Bailey's husband is having a surgery she doesn't know about, and George is trying to coach her through the labor. He does a wonderful job, sitting behind her and helping her breathe every step of the way.

Cristina's most iconic and life-saving moment was in the Season 6 finale after she and Meredith watched as Gary Clark shot Derek in the chest.

It was a scene that proved to fans that Cristina Yang was a superhero.
