i think Amma was genuine.. Thakurs actually do believe all this will result in their wishes getting fulfilled.. for now, i dont really think they have planned all this to separate KriYa.. they want her to do the rituals for their baby.. no evil plans as such yet..
and i think going by Amma's advice Krishna will keep quiet in the beginning.. but when that priest goes too far or suggests somethng which will be difficult for him to bear.. he will lose his cool.. and stop everything.
no idea about Arushi's influence on P.. and to what level it affected P.. unlike Thakurs, Saxes are too difficult to judge from their expressions and body language.. you never what is going on in their mind.. they are mostly blank..😕😆
