The intern shenanigans happening on Grey's this season brought some of that lightness and humor that Grey's had been lacking. Sometimes it worked and other times it did not. The group of interns was intriguing, but the distribution of screentime for some of them was irritating. Sam monopolized most of the intern time because of her sexcapades with DeLuca, but she was the least interesting, and Levi's shtick, while entertaining, got old and repetitive.
The thing is, of all the interns, Dahlia received the least amount of screentime and development, and most fans didn't even know her name. It was pretty damn significant that Grey's chose to add a hijab-wearing Muslim, but in not utilizing her, nor allowing her to flourish, it felt like stunt casting. Dahlia's shining moment was in Grey's Anatomy Season 14 Episode 13: You Really Got a Hold on Me, and when she delivered her quote about wearing hijab and the true message of her faith. She has a lot to offer based on the glimpses we catch of her. She's hilarious, especially when it came to her crush on Jackson, and she has an interesting rapport with Owen that could be fruitful.
Honorary Mention: Casey, veteran, Grey's first transgender supporting character, and badass hacker. He got more screentime and development than Dahlia, and his being transgender didn't feel as much like the series was congratulating themselves on the representation despite poor follow-through, thank God, but he's far more interesting than some of the others.
Talia AKA "Hellmouth" is pretty damn funny too. Her obsession with Meredith is hilarious.
