What to expect out of CBI's probe against Rhea today?

On Friday, CBI asked Rhea about what happened during her Europe tour with Sushant; when she took Sushant for treatment and also to a healer; and why she avoided calls from Sushant's father when he asked for details of his son's treatment.
Rhea was also asked why she left Sushant on June 8, and why she ignored his messages and blocked his number.
