Elsewhere, a heart beating outside the body gets everyone a little excited, and Alex is not so impressed when a new paediatric fellow begins to take his spotlight.

Take a look through our gallery below to see some photographs from the next episode of Grey's Anatomy, 'Heart-Shaped Box'...
Grey's Anatomy airs tonight at 9/8c on ABC.
