Avinash was an employee of the NDA military academy.
On Day 1, Avinash was with Major G.K. Rajput leading the trainees on a hike. At some point on the hike, Rehan injured his leg, and Avinash helped him along the way. They finished the hike at 4pm, earlier than expected, and Rajput ordered Avinash to take Rehan back to the academy's medical wing. ("4:00pm-5:00pm")
