I wrote this with pre-slash in mind, but it could very well be read as a friendship fic. (Edited and updated 6-14-2013.)
Bofur sat quietly among the company. Most had laid to rest soon after Thorin called for camp, but some, such as him, too travel-weary to sleep, were strewn about their fellow dwarves in varying stages of attention.
Bofur occasionally surveyed the others from where he propped himself against a sturdy, old tree. Having eventually decided that he was the most vigilant of the lot, he took it upon himself to oversee their safety. It wouldn't do to have come so far, only to lose their own on account of negligence. Of course, it had been a long while since their last tussle with trouble, excluding the blizzards, and the worst to fair from those nasty days was their burglar.
Bilbo, despite the layers many had shed to help heat him, had fallen ill. Bofur only wished he could have given more than some clothes and body heat in the night as he curled around the shivering Hobbit, but even he needed something to keep the chill from his bones. Now they could only rejoice that the weather was treating them well.
A shuffle of twisting Hobbit feet under blankets, and the slide of Bilbo's hair between his fingers brought Bofur's eyes down to his friend, but nothing more happened. Bilbo had only shifted in his fevered sleep, it seemed, and it had him rubbing at Bilbo's upper arm as if to warm him, knowing the Hobbit wouldn't wake.
Bilbo had kept close to Bofur more often than not since they had first set out on their journey, and the dwarf had become a friend to the Hobbit, he believed, and it was mutual for him. When they realized how ill Bilbo had become, Bofur thought it would be best to continue with Bilbo at his side. No one was surprised or protested his decision, and he was appointed the primary caregiver until their burglar recovered.
When he was needed away from where he could sufficiently watch over Bilbo, it was all too easy to get the help of another in the company. He imagined that, were Bilbo not so lost to his fever, he would be touched at how easily the others jumped to his aid.
Smiling at the thought, Bofur gently brushed his fingers through Bilbo's curls, content to watch the Hobbit sleep. He startled when Bilbo awoke suddenly, his breathing ragged. Bofur rubbed along the back of the bundle of blankets in which he'd smothered Bilbo, hoping to give some form of comfort as Bilbo began coughing.
"Easy now," he said as the hacking continued. He waited, and when Bilbo calmed, Bofur helped him to sit up and lean along his side. Bilbo's head fell into the cradle of Bofur's shoulder, lolling slightly when Bofur reached for water to soothe the Hobbit's throat.
After Bilbo drank his share, Bofur continued to hold him up, humming and murmuring long into the night to give Bilbo as much ease as possible.
Though he hoped that it wouldn't be long before the Hobbit was clear of the sickness, Bofur would never mind what he was doing now, so long as Bilbo was at his side.
