We do not know what happened at the back of the screen. She wore goggles at the airport may be to hid her emotions. If she talked to her fans may be she will get emotion and it won't look nice with other ZEE actors.
Otherwise she seems quite friendly. This is her first serial and they told her 6 months extension and also she was begin to act another character which shows her acting talent. They did not give time to her to show her talent fully. It must be very hurtful and she is very young and cannot control her emotions.
