While Meredith's life hangs in the balance, the interns each have to grapple with the reality that she may not make it. Derek refuses to give up hope that Meredith will pull through, but as time passes, Derek begins to slowly break down. Cristina takes the possibility of her death the hardest, and refuses to accept that it could happen. As Bailey and Chief Webber work to save Meredith's life, Meredith is visited by figures from her past, including Denny and Dylan Young, both of whom try to convince her not to die. Elsewhere, Addison and Alex continue to work with their pregnant Jane Doe, who has no memory of the ferry boat accident or her life prior it.
