When she regained consciousness (for the second time) after fainting on her hospital bed, she took Gopi's hands and said: "I'm glad that you came. Everything seemed so foggy earlier but now everything is crystal clear."
All this was before the rest of the family returned to her room. Then Ahem came in with the rest of the family and started is usual and 'increasingly annoying' bark at Gopi.
Suddenly, when Kokila caught sight of Radha, she started acting up, confusing Rashi for Jigna, asking Hetal who Gopi was, etc...
For that reason, I suspect Kokila has a plan.
