April is seen in the OR operating on Kathleen Kane along with Callie, and they lose the patient. The next time we see April, she's out of her OR cap and gown and talking to Jackson about passing her board exams. In the very next scene, she is wearing her OR gear again, telling the Kane family that Kathleen died.
Arizona can be seen wearing a red dress, but she does not have on her prosthetic.
When Christina is standing in the living room looking over the sleeping interns, the pizza box is half covering the bowl that Leah has her hand in and in the next shot of the (still sleeping) interns the pizza box is laying next to the bowl.
After Callie declares the time of death, the manual ventilator immediately disappears from the patient after being visible for several seconds (with the other doctor using it).
