Dear Cordy,
Absolutely correct, Pia's has become one of the most non- believable character.
To display such pathological, obesessive jealousy and greed, she is the one character who is definitely suffering from a mental disorder.
because her actions vis-a-vis JW and BW are now too over the top to be the actions of any sane person.
Partly the blame may lie, as soemone else has also pointed out, with the limited range that RC is able to display. the lack is even more apparent when she is pitted against actors of RK and PD's calibre.
But the real culprits have to be the so-called creative team.
They have been unable to sustain a story shorn of its usual K-twists, K-masala and K-Vamps. and so, they have settled for the tried and the hackneyed formulas.
