Sadie Trouble: Meredith’s old pal Sadie, played by Melissa George (whom you may remember hating as Vaughn’s treacherous wife Lauren on “Alias”), came to town as an intern, and her closeness to Meredith immediately irked Cristina. Sadie turned out to be aggressive, attention-seeking, and a bit of an exhibitionist. When she invited herself to Lexie’s intern practice sessions, she threw off her shirt and sliced her shoulder open so someone could practice stitching her up.
Meanwhile, Meredith noticed McSteamy noticing Lexie and sent Derek to tell him to lay off. Derek did, which had the obvious effect of making McSteamy even more interested. Cristina busted the interns, though, and told them to quit Frankensteining their way through minor surgery on each other.
Pretzel Day: The gang tried to straighten out grisly accident victim Twisty Man, who got stuck in a garbage truck and spun around until he was impaled on his own leg. (His heart was in his throat! And other bad jokes.)
Smell of the Hunt: Dr. McArmy’s testy relationship with the Seattle Grace staff continued as he was inclined to abide by Twisty Man’s wishes not to have surgery that wouldn’t help him walk, while McDreamy and McSteamy insisted Twisty needed the surgery just to ensure that he’d remain alive. Eventually, Callie got excited about making him a new titanium leg, and Twisty agreed to surgery. Unfortunately, Twisty died on the table, and Callie’s sadness about Hahn's depature and generalized confusion led her to an operating-room breakdown. And then at the end, McArmy kissed Cristina again. For no apparent reason again.
She’s So Unusual: Mary McDonnell showed up as an oddball heart surgeon named Dixon. Her obsession with rule-following annoyed Bailey, until Bailey figured out that by getting the Chief to declare new “rules,” she could get Dixon to do what she wanted. Bailey was (rather foolishly) caught off-guard when Dixon later explained that she has Asperger’s Syndrome, but knew she’d been the butt of jokes all day. Oops.
The Telltale Heart: This episode brought perhaps the most powerfully hokey parallel the show has ever drawn between patient and doctor. Dixon was scheduled to do a replacement “piggyback” transplant (where a donor heart is attached to the patient's heart) for a Navajo patient who regretted even having his first transplant, because he felt haunted by the donor’s spirit.
Get it? His heart was haunted, kind of like Izzie, who was stalked all over the hospital by Ghost Denny. Things turned out okay for Haunted Heart; his own heart came back to life once the mischievous one was removed. The haunted heart was returned in a jar (organs in jars: the show’s new signal of a happy ending) so that the appropriate rituals could be performed and the spirit set free. Izzie, on the other hand, couldn’t put Ghost Denny in a jar, so he eventually convinced her to make out with him, thus making him seem surprisingly real for an apparition.
