Yesterday LF during the task was mostly muted, so it's impossible to figure out what transpired and what was the issue between Teja, karan and Umar. Though much before the task started karan, umar and Shamita were strategising and clearly Teja wasn't part of it. But as said before, Teja had a totally different approach to tasks, whereas the other 3 prefer forming alliances to play the task.
Also Teja is angry at karan coz it seems he told umar in front of everyone that learn from Teja doosro ke kandhe par bandook rakh ke kaise chalana.
