These two are the epitome of mentor/mentee goals. Miranda Bailey came to Seattle Grace as a soft-spoken, mousy intern, and with some guidance from Richard, she blossomed into a badass surgeon. Richard took to her early on and put his all into grooming Miranda Bailey to be his successor.

The pair has gone through hell and back together. Their relationship has experienced some turbulence and personal drama, but Miranda will always be Richard's "work wife," and Richard will always be her father figure.

Burke and Yang are another example of a romantic couple who also had a mentor/mentee relationship, too. Cristina came to Seattle Grace with her heart set on Cardio, and she was drawn to Burke because of his skill. She quickly became an apprentice to him, and when he was facing a career-ending injury, she covered for him.

Their romantic relationship didn't quite work out, but they always had a mutual respect for one another and were connected through their love of cardio. Burke left her at the altar, but he returned years later to offer her the position of a lifetime running his hospital in Switzerland.

Despite both being in love with the same woman, these two formed an unlikely friendship and mentorship and eventually became one of the greatest work relationships of the series. After noticing Jackson's natural skill in plastics, Mark took Jackson under his wing and taught him everything that he knew,

The duo even dubbed themselves the "Plastics Posse." One of the most emotional scenes of the series was when Mark gave heartfelt life advice to Jackson while on his deathbed. Mark molded Jackson into the best plastic surgeon in the country, and Jackson became Mark's legacy.

Arizona and Alex are another unlikely duo. She's chipper and bright, and he can be a curmudgeon, but together they make quite the pair. No one ever expected Alex Karev to become a Peds god. A lot of the credit for that goes to Arizona. They became quick friends, and he's her most trusted partner when taking on cases involving tiny humans.

Is there anything more magical than Bailey and M.A.G.I.C? Who can forget the early days of the series watching Bailey dole out tough love and feign disinterest when it came to her interns. Miranda may have been hard on Meredith, Alex, George, Izzie, and Cristina, but no one can argue that she didn't love them. In fact, they were like her children.

Bailey walked Meredith through her first pregnancy and even delivered her namesake, named her own child after George, performed surgery on Cristina, scolded Alex after he nearly went to jail, and came up with ways to keep Izzie alive when she was battling cancer. She's down to two members now, but the mutual love and respect between Bailey, Alex and Meredith is still one of the best things about the series 13 seasons later.

April was always the doctor who worked hard, but she wasn't taken seriously by her peers. When Owen went overseas for another tour, April, needing a change of pace and a break, went along with him. When they returned, she was a better, more confident doctor and she excelled in Trauma. The pair runs the Trauma floor, and Owen even chose April to be his Best Man at his wedding.
