When the artist is being asked questions by Brass, the headphones round his neck are angled, one shot, straight the next and then angled once again.

More of a technical nitpick - when Riley is giving the young boy CPR at the end of the episode her technique is wrong. In cases of oxygen deprivation and child cases there should always be 5 breaths before the start of compressions - she did maybe 2 at most, and the use of two hands on a child of only 9 is extremely debatable - as the child technique of using only one hand is basically mandatory until at least the age of 8.

Title: Art Imitates Life

The title is an odd twist on the way things are supposed to be: Art should imitate Life. However Oscar Wilde once commented "Life imitates art far more than art imitates Life", snidely commenting on the quality of art in doing its job. As a result, the term "Life Imitates Art" has become a cultural meme, though the opposite is generally supposed to be more true.
