What I don't understand about Teji is that a few episodes ago she was light-heartedly teasing Viaan that when he falls in love he'll demonstrate that by taking his beloved's side over his mother's. And then when he does, she's suddenly shocked and traumatised by it 🤔
I mean, I do understand this, because she's a hypocrite and showing herself up to be very much in the mould of the usual contingent of ITV MILs. Teji doesn't yet know that Viaan is starting to have feelings for Katha but she must sense there's something there beyond a boss protecting his employee. Perhaps when she teased him about falling in love she expected him to do so with a pliable, malleable woman who would forever be second in his life to her. Clearly she wasn't expecting him to fall in love with a) a single mother, despite her oh-so-noble earlier thoughts about single mothers, and b) a woman who would openly 'defy' her, the primary woman in Viaan's life.
It's interesting to me that Teji's first thought about Katha is that she's one of 'those' single mothers who traps unsuspecting men and steals them away from their families - the irony is that Teji herself was a single mother (and presumably expects Katha to be like her and wallow in the memory of her first husband forever), whose husband was 'stolen' from her.
I think that just like Viaan is traumatised by what his father did, and his entire personality as an adult has been shaped by his childhood, Teji too is in trauma. She hasn't recovered from her husband leaving her, deprioritising her, so she relies on Viaan putting her above everyone and everything else, and refuses to acknowledge that he too has feelings (and strong ones, at that) about his father and his betrayal. She expects Viaan to run around her, fulfilling her every wish and desire, for the rest of his life, all the while berating him for "choosing" not to marry, as if him doing so wouldn't cause her to throw her toys out of the pram every time he prioritised a future wife instead of his mother. And the about-turn on Katha is clearly because she is a strong and independent woman who will not be afraid to speak her mind or say her piece, and won't be relegated into the background simply to stand around and watch the Teji-Viaan show.
It is fascinating, from a psychological point of view, to see how the effects of intense trauma play out in different people. This was the case with Ishwari as well, who people keep likening Teji to. She also had severe trauma from her past, which bled into her children's psyches and manifested in very different ways. It's all very interesting, except that ITV usually doesn't like to expound on this beyond the basic "they had a hard life, hence they act this way" trope, and no one seems willing to take it a step further and have the characters realise this flaw in themselves and take steps to rise above it. If they do in this show I will be very pleasantly surprised, but I expect they'll keep it at the level of "Teji thinks she's right but oh look she's actually the villain", which is usually more digestible for an audience.
Thanks for the great discussion topic, OP!
