Harry Prepares for the Mission and Informs Ron and Hermione

After leaving Dumbledore's office, Harry rushes to the Gryffindor common room to grab his Invisibility Cloak and quickly informs Ron Weasley and Hermione Granger about his upcoming mission. He gives them the Marauder's Map and the bottle of Felix Felicis, instructing them to keep an eye on Draco Malfoy and Severus Snape while he is gone. Harry urges them to gather members of Dumbledore's Army to assist in the surveillance.
