It feels very real, I mean, you feel like youre stepping into a real hospital, Shum Jr. marveled. Theres so many nurses and other doctors walking around, it really doesnt differentiate between reality and the Greys world. So it was nice to step in there.

As for donning the iconic Grey Sloan Memorial scrubs and jacket, Shum Jr. said its like a cape, man, its like a little superhero. Everyones a superhero in this, theyre saving lives but theyre also dealing with a lot of inner turmoil thats happening in their lives and in each others relationships.

Despite the heavier moments that can occur in the medical drama, Shum Jr. teased, Its bringing a lot of the fun back into the interactions with different characters.
