Bubba had been enjoying his second year at Hogwarts, but things took a turn for the worse when Harry had a vision of Sirius being tortured by Voldemort in the Department of Mysteries. Harry, Ron, and Hermione decided to go to the Ministry of Magic to save Sirius, and Bubba was right there with them.
They arrived at the Department of Mysteries and found themselves facing off against a group of Death Eaters. Bubba immediately jumped into action, firing his guns and taking down several of the Death Eaters.
But the Death Eaters kept coming, and soon Bubba found himself outnumbered and outgunned. He was forced to retreat with the others as they made their way through the mysterious and dangerous rooms of the department.
Finally, they found themselves in the room where Sirius was being held. Harry ran to Sirius, but they were ambushed by Death Eaters. Bubba fought bravely, but he was no match for the powerful magic of the Death Eaters.
In the chaos of the battle, Sirius was killed by a curse from Bellatrix Lestrange. Harry was devastated, and Bubba felt like he had failed his friend.
But Bubba didn't give up. He continued to fight alongside Harry, Ron, and Hermione as they battled their way out of the Department of Mysteries. In the end, they managed to escape, but not without losing one of their own.
Bubba felt the weight of Sirius's death heavy on his shoulders, but he knew that they had to keep fighting. He vowed to continue to protect his friends and do whatever it takes to defeat Voldemort and the Death Eaters once and for all.
