Clarifying for those still mistaken - Hari DOES NOT look like the sister

I'm writing this clarification in a separate post coz I keep seeing people complaining about this though it's been mentioned multiple times in the responses.
Hari doesn't look like the sister. The only thing that's same is the hair color. The mother knew it was not her daughter when she brought the child into the family. But she was mentally unstable and suffering from delusions which is why she mistook Hari for her daughter when she was having one of her episodes. The brothers were very clear that Hari doesn't look like their sister and is not their sister from the get go. They resented her for getting all their parent's attention though she wasn't biologically related. So, can we now stop arguing a non-existent point and move on to other things that make you uncomfortable?
