Dalton Marks is a patient at Grey Sloan Memorial Hospital. He is married to Karen Marks.



Dalton and his wife Karen came to the hospital when he started suffering from having a nasty breath. Stephanie and Jackson ran some tests and took scans, revealing that the muscles in esophagus were working against each other instead of working together. The esophagus wall formed a sack, where Dalton's food was being kept, and that caused his bad breath. Jackson explained a minimally invasive surgical procedure to solve the problem. He explained the risks of the procedure, a small one being damage to the vocal cord nerves, meaning he wouldn't be able to speak anymore. After hearing this, Dalton blurted out that his wife had a very cute butt because he didn't want anything to be left unsaid in case he'll end up unable to speak ever again after surgery. Another confession he made was not ever having really liked her brother, after which Karen jokingly asked how soon the surgeons could put him under.


On their way to the OR, Dalton made more confessions to his wife. Her purple dress did make her look fat, and he confessed he lied when he said it was pretty. He wanted his last words to be honest. He then started singing "It Had to Be You", which is their song. The wife jokingly asked Jackson to cut the vocal cords when they arrived at the doors Karen wasn't allowed to pass. Dalton then asked her to come closer and whispered something into her ear. Karen then kissed him and he was taken to the OR.

In the OR, Jackson tried to get to Dalton's esophagus laparoscopically, but when that didn't work he decided to go in surgically through the neck. The nurses prepared for that procedure while Jackson and Stephanie started thinking out loud about what Dalton whispered into his wife's ear, deciding it was most likely that he loved her. Bokhee then informed them the patient was ready, and Jackson started cutting into Dalton's neck.


After the surgery, Jackson informed Karen that everything went fine, even though they had to go in surgically. Dalton would have a fresh breath again from now on. Stephanie noticed how Dalton was waking up, and his wife greeted him. Suddenly, Dalton had a stroke, and while Jackson examined Dalton's pupils, Stephanie paged Derek Shepherd.

Derek later explained to Karen that Dalton had had a massive stroke that dislodged a blood cloth in the carotid artery during surgery. The post-operative stroke is a rare outcome for any surgery, and he assured her they'd persue any avenue to rehabilitation even though he was afraid they wouldn't be able to fix it. Jackson answered Karen's questions, telling her that Dalton is awake even though he can't speak or move. Jackson assured her they'd do anything they can and apologized. Karen asked if he could hear her, which Jackson told her wasn't certain, and she then lovingly started singing their song, just like he did before the surgery.
