I had two ideas for a Malec Christmas fanfiction, so I decided to combine the two. Magnus annually dresses up as the Brooklyn Santa Clause for the children of Brooklyn. Why not? He enjoys the company of children and loves making them smile. When Alec discovers this, he suddenly becomes uncomfortable. As for their Christmas, they hold a small party at the apartment for a small group of them (close friends and family). Afterwards, Magnus and Alec switch their more special, more important gifts with each other.
