Team Galactic's mischief
Go to the center of town where the Galactic grunt is blocking the entrance to the ruins and battle him. He will flee when defeated and the town elder will come and thank you. She will prompt you to give her the Old Charm given to you by Cynthia and then she will say Cynthia is her grand daughter. She encourages you to explore the ruins.

Enter the ruins and interact with the painting in the back and Cynthias Grandma will come and tell you about the ancient pokemon and she will give you HM03 Surf but says that you need to beat the Hearthome City Gym to be able to use it outside of battle.

With Surf in hand, the Hearthome City Gym is open. Head inside and tackle the Ghost-type Gym.
The Hearthome Gym features a series of question that you must answer to move on. On each floor is a sign bearing the question and three doors that are labeled with answers to those questions. If you move through the gym getting all questions right, you won't have to face any trainers on your way to challenge the leader, Fantina. The answers to the questions in order are: 15, 40, 39, and 15.
