Trisha might be pregnant, so she blackmailed Neha after encroaching upon the secret affair neha had with her dad into producing a report for her. This report itself which mayve been confidential about the reason for absence thus all is in the dark as to why exactly she would dismiss herself on medical reasons, I reckon she has been hospitalized and forged her own absence,. Kushan may be in on it. The father of her child is a debatable issue. Im certain that trisha has perpetuted her own kidnap/dispearance/escape for her own little secrets.
Mere speculation however, I may be wrong, but so far i am inclined to think for some reason or another that trisha is not so virginly pur n innocent as shes cut out to be through her mums eyes atleast, (must have been the forbidden affair she was having with her cousin3 or her taunting of others or the sex book in her locker , any one of those did the trick to betray my doubt about her capacity for committing vile acts).
Indeed if im getting anyhing from this serial it is that an individual is subject to flaws as is Human nature to be tempted by the forbidden fruit, all the characters are capable of both good and bad and this can be spotted every now and then in all characters, there has been indications of desire to redeem, in Prateek to genuine affection n care lavanya with her kids n Kushaan to his son, to impatience and ignorance projected by amrita, and losing temper bykabir on his collegues.
I feel the right chord is struck with most characters, as you cant place them into a category but I worry that ith characters like amirta representing motherhood and kabir as the saviour there is tendency to heroisise in that sense, it would be more interesting to see negative aspects of these characters rather than see them fall into same old boringv trap of perfect female and heroic male protagonists. Their imperfections should be brought to the fore a bit more.
