This was something Naina told Sameer during the phone convo...I think it means something...that is...during the Mount Abu trip I think Sameer might really do things that will draw others attention to the special kind of relation they share...and I think the bet wala boys might understand the Niana as well as Sameer is completely in real wala love and may be they would want to create a rift in between...so they will reveal the bet secret to Naina...bcoz for them if they have acknokwledged that Sameer has fallen really for Naina...then more than losing hair they know that losing Naina would be more painful and they would want that..😕...
