It was a Saturday, while he was taking a walk with his sister, that Arthur realized that he didn't know everything about Ariadne.

He knew that she played Dorothy in her school's production of The Wizard Of Oz when she was eleven , that she twisted her ankle when she was twelve while she was playing soccer. He knew she helped build the set for her high school's production of The Sound Of Music and that's when she discovered she wanted to be an architect. Her first boy friend was Dane Cook, and she dumped him when she found him cheating on her with her best friend. Arthur knew she preferred fantasy and sci-fi over anything else in movies, and that one day she wanted to have a small house on the English country side with a white-picket fence and a dog. He knew she had a fear of horses until she was ten, and now she loved them. She use to fear heights, but got over it. She always feared spiders, and still does. Her favorite book was Dracula, her favorite movie was Dr. Horrible's Sing-Along-Blog. (He seen it once. A very odd movie.) He knew that she looked her cutest when she was concentrating hard over the smallest details of the dreams she created, that her perfect date would be a night in with a bunch of movies and take-out. He knew that he felt undeniably attracted to her.

He knew all of that about her, and he got one of the biggest surprises of his life.

His sister was telling him about how her wedding was going to be like. She had everything planned. There was a little chapel that the ceremony was going to be held in, and once she and her to-be husband left the chapel as man and wife, doves will be released. She had already asked her future sister-in-law to be her maid of honor, apparently they knew each other quite well, and said woman was picking up her wedding dress for her and making sure it fit, the woman being the same size as Lily. The reception will be held at this quaint little banquet hall that was going be decorated in soft colors.

They where passing a wedding dress shop when he saw something that made his heart stop.

Aridane stood on a small platform with mirrors in front of her, wearing a beautiful wedding dress. It had a drop waist and was strapless. Under her breasts was a wide soft blue ribbon that ran down the sides of the train of the dress. The wedding planner put a veil on top of her head and Ariadne smiled. She looked beautiful.

She said something to her fiancé and he picked her up and spun her, making her laugh.

"Arthur?" Lily asked, worry lacing her voice. "What's the matter?"

He shook his head. "Nothing. Everything is fine."

When Arthur went home after lunch with his sister, he searched for any announcement of Ariadne getting married. There was no mention at all. Not even an invitation was sent our yet.

The next day Arthur couldn't even look at Ariadne. Why didn't she share that important little piece of information with the rest of them?

They where all startled when Ariadne's phone went off. She mouthed a sorry and picked it up and hurried out of the room. Arthur was, for a lack of a better word, stalking the Mark's Facebook. The picture of the Mark looked like Ariadne's fiancé.

He refreshed and was surprised to see Lily had posted on the Mark's Wall.

I can't believe you, you fucking bastard! And a week before out wedding! You know what? Forget it. Wedding's off. Don't even bother meeting me and my brother for lunch today. I don't ever want to hear from you again. Just take your whore and leave out of my life.

So this was Lily's fiancé, not Ariadne's.

Ariadne bustled out of wherever she was talking on the phone.

"Arthur, I have to leave early. I have to meet a friend who just left her fiancé. We have to see if the wedding dress shop will take back her dress and the bridesmaid dresses. It's a pitty, her dress was so beautiful." Without another word, Ariadne left.

Arthur continued stalking Facebook, switching back and forth between the Mark's, Lily's, and Ariadne's pages.

Half an hour latter, Lily made a status update.

Damn, can't believe I thought Luke was cheating on me with his cousin. Must be the baby. Wedding's back on. Hope I can fit into my dress, (So happy the wedding dress shop/place didn't take back the dresses the sold on sales.) the BMOH did the greatest job ever of picking it out for me. I know I said I wanted a green ribbon, but blue looks so much better. And it matches the Bridesmaids dresses much better.

The Luke updated his status.

Note to self: Next time, tell Lily when I'm meeting up with family. There's a chance that she, or one of her friends, will see and she'll freak out.

And then Ariadne joined the status-updating craze.

These people are driving me insane. I have other things to do then say "… That's our cousin, not his mistress." On the upside, I have dinner plans with someone very special (And needs to pull that stick out of his ass.).

So Arthur found out three things that day.

1) Lily was engaged to the Mark.

2) Lily was pregnant.

3) Ariadne was going to blow off their dinner plans to either a) spend time with her fiancé, or b) cheat on her fiancé.

When he met Lily and Luke for lunch, they decided to spring a question on him. Well, actually, two.

"Arthur, Luke and I have been talking..." Lily started, bouncing in her seat, hand intertwined with Luke's. It was just a painful reminder that Ariadne wasn't going to be his.

"We where wondering, if you'd do us the honor of being my best man at the wedding." Arthur agreeded to be the best man. It'll get his mind off of Ariadne. That was a welcomed change.

"Arthur, I'n pregnant, and we want you to be the god father." Athur nearly fell out of his seat at that. Almost.
