 Feeling that he put the hospital before her, she breaks off her friendship with him, causing problems with them being able to work together that are later made worse by Cristina's own relationship troubles with Owen (During this time, Cristina tells Owen that he has to grant Teddy her anger, to which an enraged Owen lashes out the hypocrisy in the situation, given that when Cristina discovered she was pregnant with Owen's child, she told him that keeping the pregnancy was non negotiable and wanted to pursue an abortion, despite Owen's desire to have a child, and his pleas to keep the pregnancy, points out that Cristina never "granted him any anger" over what he thought was her selfish decision).After a particularly bad case, Dr. Bailey sternly tells Teddy that what happened with Henry was not Owen's fault and that Teddy knows this and needs to get over it, which pushes Teddy to behave more civilly towards Owen, but she finally lets go of her anger after she desperately begs Owen to convince Cristina (who by this point has broken up with him) to not transfer away from Seattle and is left shocked and silent when Owen furiously tells her he will not do that because he and Teddy are only co-workers and, as she made very clear, not friends and therefore she has no right to ask him for any help or favors.She and Owen eventually make up in the season finale.
