From yesterdays episode it looks like TS does not have anything to do with the Sahil murder or the burkha lady. It seems Bani really is in danger - bomb blast etc. Two things can happen after yesterday
1. From the treatment he got yesterday might trigger his pshycosis. Till now he has easy access to Bani but now he might get negative.
2. Or they might show that Tarun has indeed recovered and is trying to genuinely save Bani. This might lead to a platonic BT friendship post JB separation.
In both cases I think Jigz will act as instigator.
Let's see which one the destrucitves have in store for us.
