Why can't Sadi win?

Sadhna can win the competition because:

1. she is participating for a better reason

2. she is well-determined and is going to work hard

3. she has a very good teacher

4. ragini's ankle is hurt, so she might not be able to practise enough

5. ragini's has also not been out of dance practice since last year

6. ragini's hurt ankle and current unstable, less confident state of mind might prevent her from performing very well in the competition

And I would love to see Vasu's face when Sadhna wins (although the best would be if both sisters re-unite and perform together at the competition).
