Gravity

It's a bad day for Abby, who's missing the still-absent Luka, when Joe is brought to the ER after a fall and is unable to reach Luka. Elsewhere, the day puts family first as Morris cares for a frightened child and Pratt defends his brother. Neela returns to work, and Moretti returns from a conference. A patient's mother gives the ER staffers makeovers in appreciation. The ER gets a new receptionist.
