So, I'm a bit of a Fred/Alicia (Fradlicia?) fan, and I decided to write this story. Sorry if it's super sad, but… well, there here it is.

Alicia's POV
"Fred," The words were out of my mouth before I could stop them. Fred turned back and looked at me. I was the last person left in the Room of Requirement because I had hung back, hoping to speak to him alone.
"What Alicia?" He asked, sounding genuinley curious as he sauntered over to me, looking so perfect I wanted to kiss him right then.
I took a deep breath. "Fred, we're going into a battle. We could die." He nodded slowly, looking confused. I continued. "I think... no, I know there are some things I want to say to you. Things I want you to know, in case... in case we don't make it out of this."
Fred smiled down at me. "I think I know what you mean Alicia." he said, giving me courage to continue.
"Fred, I... I love you." I said.
Before I could do anything else, he drew me into his arms and murmered four words to me, "I love you too," before kissing me.
After about a minute, he withdrew, and said "You're beautiful, Alicia. I love you, and I want you to know that if we don't make it out alive. But now, now I've got to go kick some death eater butt." He winked at me, and turned to go.
But just as he left the room, I called out to him "I love you too, Fred."
That was the last time I saw him alive.
