I just think Neha was bitter with the Khan Sisters for exposing her during the task and how her mean side was already out in the open.She just needed a reason to not let Khan Sisters become the captain because she knows how they are not the ones to get manipulated easily.
Dipika was completely right in saying how Surbhi should be disqualified for damaging the property yet Neha never disqualified her. Damaging the property is not a joke and you should face the consequences for it which Surbhi didn't.
Dipika and Srishty were perfect for being fair in sending neha top the jail as you should not support your friend or team member when they are wrong and should call them for their wrong behavior on their face which they did.
Neha just nominated herself for kaal kothri because she knew how everyone knows about her true intentions, so it is better to accept your mistake and go to jail so that,people assume how she realized her mistake and is feeling guilty about it and this topic is not raised on Weeknd Ka Vaar,
