Sid is coming across as a confused individual. To some extent it is understandable that until now he never cared much about his family and now somehow he is getting pulled into family matters. But he can’t blame Mithai every time just because he is a pendulum and cant make up his mind.
Actually instead of just Mithai it should have been Dadu who could drill some sense. Dadu cant always put the burden on Mithai to fix his family problems . For god sake she has been there for just couple of months and she is disliked by most family members. Sid has mentioned multiple times that he does not trust her still dadu expects a young girl to solve everything with a magic wand. Unki samajhdari ko kya hua hain.
This is what i dont like in serials when one person is burdened with everyone’s problems and that person accepts that happily as if there is no other purpose in life.
