Malini even forgot that when Apu n RT did not want her to attend NishVi's function it was Imlie who insisted on her staying at T house . That was the last time M was normal with her. Since Apu called her after Adi fell sick, Didi ki umeede jagi... N seeing Adilie together she started lashing out at Imlie. She did not even acknowledge her or shown empathy towards her after Imlie learning they are sisters..
Imlie has always fought for others and never herself. This has been Adi's pet peeve if I can call it that for the longest time. She puts others ahead of her, period, that is who she is.
In the discovery of Adilie and subsequent dislike for Imlie, apu seems to have forgotten that Malini likes KC. Has forgiven for her friendship with KC and is suddenly her golden bahu? Talk about pea sized brain. At that time, Dd shamelessly took Imlie's help to maaro entry into the Dts for NishVi shaadi and ran away scared too as she did not want to meet Mithi. So many lies n subterfuge, yet she is able to convince herself she is doing the right thing... for Adi... BUT she is stressed, wants to protect Adi's reputation but she is the only wife.
As long as she was a servant and a nobody, she was best friends with Imlie but once the truth came out, she sees her as a competitor who has taken away her fave toy and shattered her dreams.
At Bold yes.. so true Imlie was hurt and not a word of empathy here.
