So, how about coming up with some humorous ways to teach her a lesson or making her vanish?
Mine are:
Dadda ji's bhoot shows up and divorces her after which he gives her a parting gift, a flying broom
or
Mishti creates a shrinking machine and accidently shrinks her into a size of an ant. She is then chased by a cockroach as she runs for dear life
or
Gabbar Singh comes to town and kidnaps Kaveri because he believes she was his Basanti in last janam. He brings her to his adda and makes her dance to "Haan jab tak hai jaan"
or
Neighbour's doggie Snoopy asks to marry Kaveri and Raj banna does her kanyadaan
or
Kaveri accidently wanders off to an alien ship and ends up on Mars
