Ved leaves for his home and next morning Ved wakes up on time, completes the morning chores, wipes the car, ignores the transgender on the way, lets a female colleague into the lift—all this happens on his way to the office.
Tara, after finishing a business meeting at Oracle in Tokyo, heads for refreshment where she finds a note titled "Don Returns".
