In yesterdays US episode, Abhi praises Sia to high heavens. That probably went to her head, and also took her back several years. All I can say is she is child-like in her enthusiasm and naive behaviour. She loses all her so-called maturity after this episode (from reading sree's wonderful updates, since I haven't yet seen them).
Even the elderly Saxena's are ignoring Aastha, and that probably goads her even more. Only Saurabh seems to have some affection for Aastha. He acts superbly in this (US)episode
I totally agree with you !
