Hungover April

Meredith Hiding Out
Mark served Meredith and David coffee when the former went to the bar to hide from the reporters at the hospital and to calm her nerves before her presentation. While the two customers were playing darts, Mark inquired if they were looking for something stronger to drink, but Meredith turned him down because she had her presentation coming up.
