Will laxmi be able to come in holi party ?

i think yes
she will come in agnihotri mansion
Arjun will convince his dad
by hook or by crook

or he will say that he wont celebrate holi if laxmi doesnt come
or dadi will convince rv

I think the later will happen.. either dadi or he wont celebrate.. which might make his dad reconsider his decision and allow lakshmi to be invited.
