Fili was walking about the desolated, bleak halls. For a few minutes, he's been waiting for his brother to return to the treasure room to help their search, but with his prolonged absence that lasted for an hour or two, the blonde was starting to worry. He tried to convince himself that Kili was resting, but no doubt he would be looking for Delva. The youngest was attached to their godmother by the hip, it would seem. That gave Fili an amusing feeling, but he still worried. With Thorin getting impatient, at each and every minute, Fili just realized that they were not safe. It didn't feel like wonder in this mountainous structure; it only felt like an unsettling anger thriving in the stone walls. Something was terribly wrong...he could feel it. 

Just before he could take a left at an intersected hall, the blonde could hear voices; they sounded hushed, so his instincts told him to turn right, right towards the source. He kept his footsteps light, and the voices got louder, getting clearer, as it seems to sound more like an argument when he got closer. He heard his uncle's voice, then...Kili? What was he doing talking to Thorin? Now the brotherly impulses took over, already becoming worried about his little brother being in his deranged uncle's presence once again. His thoughts were cut off when he heard a slap, right before Kili could even finish a sentence! Fili actually despised the dwarves who belittled Kili when they were younger. They lead to the blonde getting involved in fights to cover his little brother, and the aftermath resulted in the eldest also getting hurt, just with minor scratches, cuts, and bruises; Kili looked no better. 

But this was Thorin doing the belittling, and Fili felt conflicted for the first time whether to cover for him or not. However, he wouldn't allow his uncle to furthen the damage already done, so he advanced into the room, towards his uncle and brother. "Stop it!", he shouted, coming in between them, and running to his brother's side. Seeing the bruise on the youngest's face made the blonde feel betrayed. "Oh, Kili", he breathed in a mix of anger and sadness. "How could you?", he asked his uncle. "Striking upon Durin flesh and blood; answer me!", Fili was angry; his voice was reverberating off the walls. He couldn't imagine how Saeril would react if she were here.
