Drizzt been tracking this snake demon for some time, he being very hard to track never leaving a trail for him to follow even with his extensive years on the rangers he couldn't track this thing whatever he was many people told Drizzt many different stories though not paying attention to most of them. None despises him more then the konoha ninja and the past transgression against them that he was the sole cause of, against one own village which was basically your family how could one cause so much pain and suffering? Drizzt wouldn't be able to comprehend though he did know not to get attached to people as that was the first sign of weakness. Emotions wasn't allowed in the Rangers and Illuvatar was a strict master... Though Drizzt was better off with the training.
Drizzt had an reliable source that heard a rumour that he would be on this bridge at dawn, his informant never let him down before; after days of travel and scouting the local areas mapping down the environment for the Noldor when he returned home. Drizzt awaited in the trees for this man to show up on the bridge after all Drizzt has fought bigger demons then a mere "snake demon" though konoha warned him he was one of the legendary sannin so Drizzt took caution not to get too ahead of himself already, having his bow already formed on his back he waited to see if this thing would show....
