After they landed on the bottom of the pit and inadvertently Nagato, Dango unsteadily got back up before clearing off the visor of his helmet. "W-where did th-thish hole come from-m...?" Dango asked, much more confused about that than why Nagato was taking blame for something none of them knew about. Dango sighed quietly before flicking Nagato in the face. "Why-y are you a-apologishing," he said as he put his helmet on. "It'sh n-not l-like we knewsh about thish." There wasn't any reason for that guy to apologize about anything, and it really annoyed Dango for some reason.
Quickly casting that aside, Dango went to planning. "First off, sensei seems to be avoiding direct combat." There was an opportunity for him to strike before the pitfall had triggered, and he must have known they were there since they were yelling beforehand. Because he knew that, their teacher was probably aiming to use genjutsu. "It wouldn't have worked because Nagato had us close our eyes, so that's probably it." Since genjutsu isn't directly offensive, his objective was either to run down the timer, or split them up before taking them one by one. His wire could work as communications so that they could split up and still find each other; pulling, loss of tension, or just stopping could act as a signal and the cable could be followed towards their teammate. "So even if one of us gets caught in the genjutsu, I'll know." After organizing his thoughts, Dango attempted to explain his plan, stumbling over his speech as he did so.
