The gifts William received first thing in the morning of his birthday were something to talk about.
Jane had sent him a big bouquet of flowers, which never fit through his apartment's door as whole, along side with a note. It said, "Happy Birthday William aka Agent Brandt. Still don't know much about your likes and dislikes so decided to send you just flowers of as many types as I could find. Hope you like at least one species out of these. Let's met soon. Jane." It was written in beautiful but simple handwriting and had a smiley drawn in the end.
Benji had sent him the metal Jacket which saved, or rather, was the reason his life was going to be taken away by a gigantic fan. It carried a little note too, saying, "You survived this. Do not forget. You are no less than a superhero, dude." The Jacket was still warm to touch.
Ethan had sent a group photo of all four of them. They had taken it before going to that restaurant where they parted. William had wanted it for long time but never got chance to ask for it. It didn't have any note. It didn't need any. Seeing those tired but happy faces of them was the perfect gift. William couldn't be happier.
Ethan arrived at his place late that night with a champagne and a cake and a bunch of new stories of his recent missions.
