How do the incidents that take place with Bakha and Sohini at the temple reinforce the text's claims about power and status?

Bakha is very curious about what is inside the temple because the caste Hindus use their power to exclude outcastes from religious ceremony. When he is discovered on the steps, he is terrified--he knows that the reaction will be an angry uproar. He is also immediately concerned about his sister's safety, because he knows that he did not touch the priest who is claiming "pollution" by touch. This indicates that, despite Sohini's innocence in the matter, Bakha knows that the anger of the caste Hindus will be focused on her due to her outcaste status. All of the power is clearly vested in caste status, and Bakha and Sohini are powerless in this situation.
