She knows her stuff well

When they arrived outside, Hugo was going to his car when he saw Elio not taking any further steps. This only meant one thing, the latter was not satisfied with the answers he had received from the doctor and he obviously had to know what he had in mind forto know if it wasn't going to wake up his girlfriend's demon because he had no doubt that Carmen's change came from her. She had certainly noticed that the latter was doing better and she was also afraid that she would denounce her, which is why she had certainly done that.

“You can leave but I’m still staying,” Elio told him.

“You stay here waiting for what? That she finally recovers? Elio, this is definitely going to take days and what are you going to do during all this time, tell me. You have to go back to work in the meantime.”
