Lindir, with a royally confused expression, went up to Gandalf. Gandalf gave a quick summary of what was going on, then as Lindir nodded Gandalf placed the hat on him.
"You are definitely not Gryffindor, nor are you Ravenclaw. You are not brave, nor do you seek knowledge. Hufflepuff, perhaps, as you do possess somewhat questionable loyalty, and you are a hard character to place, but you are very cunning and nosy at times. You have a noticeable penchant for blackmailing as well, and you are ambitious. SLYTHERIN!"
Lindir handed the hat back to Gandalf, and got a silver and green ribbon. He returned to his seat, still with red paint on him.
"Treebeard!"
This is based off of a medley of my characterization, Erestor's characterization, and Lily Lindsey-Aubery's characterization for Lindir.
