Sure, you're familiar with "Grey's Anatomy," the longest-running medical drama in TV history that premiered on ABC in 2005 as a humble mid-season replacement. Shonda Rhimes' soapy, steamy, and delightfully over-the-top hospital drama, led by Ellen Pompeo as the eponymous Dr. Meredith Grey, follows five surgical interns as they begin working at a major hospital in Seattle; after those interns become residents and attendings (or, in at least one case, die), the show keeps introducing new incoming intern classes as they're thrown headfirst into one of the most daunting and intense professions around. So, uh, what the heck is "Grey's Anatomy: B-Team?"

In January of 2018, a webseries called "Grey's Anatomy: B-Team" hit ABC.com, giving audiences a closer look at the 14th season's intern class. Introduced after the first few episodes of said season, Dr. Levi Schmitt (Jake Borelli), Dr. Sam Bello (Jeanine Mason), Dr. Casey Parker (Alex Blue Davis), Dr. Vikram Roy (Rushi Kota), Dr. Taryn Helm (Jaicy Elliott), and Dr. Dahlia Qadri (Sophia Ali) all start working at the hospital now called Grey Sloan Memorial, and just like the intern classes that came before them, they make mistakes, run afoul of their superiors, and learn along the way. The six very short episodes of "B-Team," all of which ends up being under 20 minutes in total, give us more insight into this intern class -- so, here are five things you need to know about it. (Also, you can watch the whole thing on YouTube.)
