Today's instalment of the BBC One drama saw Corfield's character Freya Wilson turn hero as she attempted to save colleague Kevin Tyler (Simon Rivers) from a blaze at his girlfriend's home.
Both were soon rushed to hospital, where events took a tragic turn as one of them flatlined…
Although Corfield is currently keeping tight-lipped about her character's fate, she discussed the game-changing fire scenes with fans on her Twitter page this afternoon (June 18).
Posting up a picture of her kissing co-star Simon Rivers on the all-important filming day, the actress commented: "The shot all Freya & Kevin fans hoped would happen! Here's me with the wonderful Simon Rivers. Both emotional wrecks."
Sharing a second picture, she added: "And life goes on... on the other side of the camera at least. THANK YOU all for your amazing comments about today's ep."
Doctors fans now have a three-week wait to find out who lived and who died as the show is on a transmission break.
