I thought I might as well give these a shot too, when I think of more I'll be sure to add them ^_^ They'll all probably be in 2nd person like the ones below.
Not every part with have the same characters, I'll do as many as I can think of or just the ones I think fit.
You fall asleep on his shoulder
Thorin:
He noticed your head starting to bob as you tried to stay awake. He let out a deep chuckle and slipped his arm securely around your waist, pulling you against him and putting your head on his shoulder.
"Rest, my love." He whispered and kissed the top of your head.
Fili:
He was carving something out of wood when you slumped against his side. He smiled down at you as you looked up at him with sleepy eyes.
"Get some sleep, my darling, I will watch over you." He whispered stroking the side of your face as your eyes closed.
Kili:
He noticed you resting your head on your arms beside him. He reached over and put a hand on your back. When you looked at him he smiled.
"I'm sure I'd be a much more comfortable pillow, wouldn't you agree, my sweet?" You scooted over to him and leaned against him. He moved a lock of hair behind your ear. "That's better, isn't it?" He whispered before leaning down to kiss your temple.
Dwalin:
He looked down at you as you fell against him, barely able to keep your eyes open. He found himself smiling fondly as he stroked the back of your head gently. He glanced around the camp and when he found no one to be watching he slipped his hand into your, grinning when he saw the smile on your face.
I might add more if I can think of them. If you have a request just tell me. ^_^
