Bala gave Raman a condom packet saying he confiscated it from a student during tuition class. Can a teacher bar a student to use an aid to have safe sex? Even if he can considering the student a minor, wouldn't it be natural to return this confiscated thing to the tuition center authority and inform the student's parents? But keeping it in his pocket sounded odd. Raman's expression of disbelief when Bala showed it to him was spot on. Raman was busy with his own dilemma plus he trusted Bala a lot, so he bought his excuse. But in reality, this contraceptive aid might be connected with the unresolved Bala mystery. His advice and actions suggest that he might not be so sidha-sadha as he appears.So, I think the Bala mystery dates with Ms. R might get revived soon.
