This is not exactly a warning but more of a combination of an alert and a spoiler. After the blessed horizontal line, Realn walks in to find his parents engaged in intimate matters. It is a brief scene, lasting only a few lines, and very nondescript but I just thought I would let you know.
"He has been what?" Realn asked, almost dropping his fork.
Thranduil looked at him patiently. "For the second time, I told you; he has been adopted."
"What?" Legolas said, as if hearing for the first time. He was seated around the dinner table with his family, enjoying the last meal of the day.
"Stop antagonizing your father," Cinwe cut in. "Thranduil, say that one more time for me."
"Web has been adopted," Thranduil said.
Brenen smirked. "I know. Zionel told me. I went out to see if he wanted to tramp through the woods with me but he shut the door in my face and told me to go away as he was with his new little brother."
"I am sure you felt that way," Cinwe said complacently. "But I know Zionel and he has excellent manners."
Brenen pursed his lips. "Then I am guessing you will not want to hear about what I did as way of getting revenge."
Mykar chewed his mouthful of food. "Was Zionel's mother not once a rival in love with you, naneth?"
Cinwe frowned at him. "And where did you hear such rubbish?"
"Anialia told me she had come close to marrying Thranduil," Mykar replied.
Cinwe folded her arms. "Not a word is true. She never had a chance. I roped your father in with one look!"
"Is that true, ada?" Mykar asked.
Thranduil sipped his wine.
"Well?" Cinwe pressed.
Thranduil lowered the cup. "Your mother and her rival both captured my attention. It is hard to say who would have one me for Anialia found she loved another."
"I still say I won you with one look," Cinwe said, and picked up her fork.
Mykar grinned and reached for a biscuit.
"I hope Web will be happy," Legolas said.
"He will," Thranduil said, covering Legolas's hand with his own. "Galleon and his as rich in love and happiness as we are. He will; have a good home."
"I wish I could see him," Legolas said.
"I do not think that will be possible for a while, Legolas," Cinwe said. "Web will want to spend time with his new family."
Thranduil cleared his throat. "Well, the adoption has not been approved and put to paper yet. I thought I would go down to Galleon's house in person and do the honors. And as our lives have been a part of Web's since the day he came to the healing wing, you can all come with me. With the exception of your mother, of course."
"Why must naneth stay at home?" Realn asked in surprise.
Thranduil leaned back in his chair and assumed a coy expression. "Well, it occurred to me your mother's claim of roping me in with one look might not be as strong as she says. I am not sure she could stand to meet her old rival in love in the eyes without feeling flames of jealously."
Brenen reached for his napkin as he broke down into tears of laughter, attracting the eye of the woman seated opposite his father.
"Well, I can assure you," Cinwe said, slamming her napkin down on the table, "Your father's fantasies are not true. I am coming and I shall look Anialia in the eye with as much grace and respect as I did the day I was married to your father!"
Brenen coughed into his napkin and wiped his lips with the fawn colored cloth. Judging the meal to be over by the sight of the empty dishes and platters around him, he pushed back his chair, saluted Thranduil, bowed to Cinwe, and skipped out of the room.
The scraping of chairs sounded and a stampede followed as the three quadruplets followed after their brothers. Only in the door did the four elflings look back and, suddenly remembering, called, "May we be excused, please?" as they vanished down the hall.
"No!" Cinwe muttered, but little elven ears were far beyond hearing.
Footsteps sounded and Brenen poked his head back into the room, inquiring, "Sorry, did you say something?"
"Nothing you would like to hear," Cinwe replied, and made shooing motions with her hands.
Brenen shrugged and disappeared as he ran to catch up with his brothers.
Thranduil looked down the empty table at his wife as Galion came in with a posse of servants to clear away the dishes.
"I suppose you are not about to apologize for the utter humiliation you put me through right before our children?" Cinwe said, with mock indignation in her voice.
"Certainly," said Thranduil graciously, rising to his feet and holding out his hand to Cinwe. "Come with me and I shall 'apologize' in the privacy of our chambers."
"It is bedtime," Mykar said.
Brenen looked at the polished clock on the mantelpiece in the family room. "It is ten minutes past bedtime."
"Are you going to bed?" Mykar asked, peering over the top of his book from where he sat, curled in the armchair.
Brenen affected to think deeply. After a moment he grinned. "No. I am going to wait until ada and naneth come and tell us to go to bed."
"You will get in trouble," Mykar said insufferably.
"You can go to bed," Brenen invited. "No one is stopping you."
Mykar thought about it. His head disappeared behind his book and he continued to read.
Brenen turned back to his game of chess with Legolas.
Realn slid out of his chair. "I am going to see if I can find them. Maybe they went out for a walk. I will ask Galion."
"Check their bedroom first," Mykar advised. "They may have already gone to bed."
"If they have, I shall stay up half the night and fashion ghosts from white linens to haunt the guards," Brenen said, brightening at the prospect.
"If they have gone to bed without coming to say goodnight, they must be tired," Legolas cut in. "And it also means they trust us to go to bed on time on our own."
"You spoil all the fun," Brenen grumbled, plunking down his chess piece on the board with a sour expression.
Realn slipped out of the room and headed up the hallway to his parents room. He came to the door and, not wishing to disturb Thranduil and Cinwe if they were, in fact, sleeping, he opened the door, keeping every creak minimized. He peered into the room and froze.
It did not take Realn long to realize he had come in at an inopportune moment as his eyes fell on the naked flesh on the bed. His heart almost halted its duty in his chest for, while he did not fully understand what his parents were doing, he did understand it was private and intimate and somewhat embarrassing to behold. With great presence of mind, he quietly shut the door lest it betray him, shutting off the sounds coming from within and tiptoed down the hall. As soon as he was out of hearing range, he broke into a run and fled back to the family room, arriving red faced upon the scene. His brothers looked at him with interest, Brenen's hand frozen midair in the move of his next chess piece.
"So, are they sleeping?" Brenen asked nonchalantly.
Realn gulped. "Um—um—no. They are busy. Very busy and do not want to be disturbed." His voice came out weak.
Brenen frowned. "Are you all right? Is this some kind of joke?"
"No, no," Realn said hurriedly. "But—um—we are to go to bed at once and—and we are not to disturb them, even to say goodnight."
"This is beginning to sound suspicious," Brenen remarked as he claimed the victory and rose to his feet with a yawn as Legolas put away the chess pieces and the game board.
Realn shrugged, unable to wipe the image of his parents out of his mind. He did not think he would ever be able to look at them in quite the same way again.
"We should rest," Legolas announced. "We have to rise early so we can go with ada and see Web!"
Brushing aside Realn's peculiar manner, the brothers went to bed.
