in yesterdays episode i think shera was purposely rude to veer, could see clearly the effort it was costing her. she knew dharam was keeping a close watch on veer, obvious by the way he had followed veer into the fair. she knew dharam would now intensify his watch even more, and if veer was caught then he would be executed and dharam wouldnt do anything saying that it was tradition. she also knew that if she asked veer to let her help him then he would refuse as veer wouldnt let anyone risk his/her life for him. she knew she could do it easily as she is being doing this kind of things from the day she was born evident by the way she used to come and go into aryanagar without even veer finding out . she had to be rude and to sound convincing had to demand money. she did hurt him but acheived what she had set out to do. veer let her help him without any arguement. he also knew she is capable of delivering the weapons better than any one of them as was evident by the what he said the next day to the shramik.
