Author's Note
So! The wedding's over, next chapter. The mission is revealed...dun dun dun! Obviously, it's going to be mostly Harry/Gwen, but there are a couple other pairings yet to be revealed. One of which will create a very complicated and interfering love triangle. Yay! So...please review, I know I say it every time, but I have yet to see anymore and I'm getting a little disappointed.
Disclaimer- I own none of these characters except Gwen

It was late the next day when Gwen was able to speak to Harry. Things had to be torn down and cleaned up. Bill and Fleur had departed for their honeymoon, and by late afternoon things had begun to finally slow down.
Ron told her she could find him under the apple tree, rereading one of his favorite quidditch books.

"Harry, about last night…"
"Don't worry about it, it's my fault. I'm sorry I overreacted." He closed the book and stood up.
"I just want you to know that whatever becomes of this, I'll be there to help." She offered.

"Hey Harry! Fred and George wanna know if we're gonna play a game of quiddictch with them or not!" Ron yelled out the back door.
"I'll be there in a second!" Harry yelled back. He turned to Gwen. "Thanks Gwen." He said, smiling, and took off towards the house.

Gwen spent the rest of the evening watching Fred, George and Ginny battle it out against Charlie, Harry and Ron. She and Hermione played referee to the game, and in the end, Ginny and the twins won, causing much cheering on the girl's part. Dinner followed soon after, a feast of delicious leftovers that no one could finish from the wedding the night before because Molly had prepared so much food. No one was complaining though, because Molly's cooking was the best Gwen had ever tasted.

They were all still sitting in the kitchen when there was a knock at the door.

"Now who could that be?" Molly wondered, bustling over to answer it. She checked her clock, making sure all of her family was safe, and then opened the door.
"Minerva! It's so good to see you! Oh you just missed Bill and Fleur, they left at about three for France, Paris you know…Isn't that romantic?"

"Yes, good evening Molly, so sorry to bother you, but I received a letter that I believe requires my attention." She looked around the room, immediately spotting Gwen, who suddenly rose to her feet.

"Minerva I don't believe I've sent anything your way recently…"
"Oh no Molly, it was this young lady here, whom sent me the letter." She nodded to Gwen, and continued. "But I have some others with me who this also concerns."

The headmistress stepped further out of the doorway and as if to make room for more. A couple seconds later Severus Snape stepped into the kitchen, followed by Draco Malfoy. The twins were immediately on their feet, as was Harry. George said something to Ginny and a few moments later she and the twins had left. Harry, Hermione and Ron made to follow, but McGonagall stopped them.

"You three should stay for this. Molly, may I have a word with Miss Jessel-Weasley, Mr. Malfoy, and these three alone?"
"Of course Minerva, Severus, would you like something to drink?" she asked, leading him towards their make-shift parlor.

After they had left, Gwen stepped forward. "Headmistress, it's nice to meet you. I'm the one who sent you the letter. I was hoping you could help me."
"Yes, of course dear. Mr. Potter, I believe Miss Jessel-Weasley has already explained to you the contents of the documents left to her by her late parents and the situation we are now in?"

Harry nodded.

"Well then, Miss Jessel-Weasley, would you be so kind as to explain to your friends here?"

Gwen obliged. It took no more than five minutes to illustrate the details to them. And when she was finished, they all looked quite flabbergasted.

"Miss Granger, I believe you have used a time-turner before? You recall?" McGonagall asked.
"Of course, headmistress." She replied, nodding.
"Let me clarify then. You are now aware that this is an immediate solution to the Dark Lord's imminent threat. As Order members, this is your mission. You will go back in time and destroy him, it's the only way. You five will be leaving tomorrow, with a detailed plan, and only each other to rely on. You must not fail."
It was them most serious they had ever seen their headmistress.

"Now, Severus will be explaining the details, but I must take my leave, there are urgent matters at the school that require my attention." She turned before she walked out the door. "The best of luck to you all. I hope you succeed, for all our sakes."
