I think next week we will see intro of Mrinali, she is trying to collect documents etc, Nisha's long street walk, A and pammi meeting, Nihaal's questioning to A, Jeeju khaatu more planing, Someone ( do not know who) will come to help A to get attorney that's all Friday may be the promo part
Quite possible the party happen when custody battle is still pending, that is why Veer was asking her to be friend for a day.
as you said may be Veer will give second thought to his action or he might find his bro's diary before he left home and get the truth that why he decided to marry Divya, how she is not behind money., but veer has taken a step ahead, now he is not going to go against himself specially when his mom's health involves.
They might show while custody battle on Veer started realizing that how Nisha bonded, not sure if judge will ask N ki with whom he wants to stay??? seeing that A has will and Vardhan's are his paternal family ( depends how Mrinali present the case)
