Fred Weasley and Weiss Schnee
Fred loved Halloween. If there was a stronger emotion than that, then Fred would definitely feel it towards Halloween. It was a wonderful holiday, and Fred was excited to experience the muggle version of it. And that included attending the party that Friday the 13th. With Weiss, of course. He was growing fond of Weiss, and was glad she had agreed to come with him.
He'd gone all out for his costume. Well. Perhaps that was a bit of an understatement. His real costume was to be revealed on Halloween night. Tonight he just donned a Pikachu hoodie and yellow pants. He'd Googled Pikachu, and decided to go with it. He just hoped Weiss wouldn't mind.
