Dennis Creevey was visiting Hogwarts and had just entered the Room of Requirement.
Dennis had asked the Room of Requirement to just give him a quiet space and keep other people out.
Dennis had a son on the way that was due in a week and the circumstance of being about to become a father had brought all sorts of emotions out of Dennis.
On one hand, he couldn't help but be proud to become a father.
On the other hand, the pain caused him by the tragic death of his beloved brother Colin had coming rushing back to him.
Colin and Dennis weren't twins like Fred and George, but they were super close.
Colin's death had destroyed Dennis on the inside. His heart couldn't take the fact that Colin would never graduate from Hogwarts.
Dennis had moved on as best he could after his initial grief, but his looming fatherhood had brought the sadness from Colin's death back to the forefront.
Dennis thought about Colin's spirit and upbeat nature and thought about what a great uncle Colin would certainly have been.
The fact that Dennis would never be able to introduce his son to his brother had brought the reality of his brother's death rushing back to him.
Dennis began to cry slowly but soon broke down completely.
All of the pain, hurt, sadness, and grief Dennis had been carrying came pouring out of him.
Once Dennis had recomposed himself, he was struck by an idea almost as though the Room of Requirement had planted it in his mind.
"Colin is never going to meet his nephew, " thought Dennis to himself, "But I hope his nephew, my son, will be able to channel his spirit, energy, and happy nature. "
And Dennis knew what his path forward was now.
"Both in honor of my late brother, Colin Creevey, and in the hopes that my son will be just like him, I shall give my son the name Colin, " Dennis made up his mind.
Becoming a father was the most meaningful thing in Dennis's life.
Giving his son Colin's name was a tribute. A tribute to a happy and loyal brother who had always lifted Dennis's spirits. Colin deserved the honor.
It was also a message, a message that while his brother may be gone physically, his spirit would never die.
Above all, it was also about hope. A hope that His son Colin would be just like his brother Colin.
A hope that Colin the son would have the same spirit, happiness, energy, and good nature that Colin the brother had had.
What better way for Dennis to honor his brother Colin than by naming his son Colin.
