Earlier, while at the hospital, Zyran had called Mila and Cher to come over to the penthouse, but he didn't give details of the reason. When they arrived, Mila was surprised to see Alvaro seated and discussing with Zyran like he wasn't going senile earlier. If Mila hadn't witnessed the scene herself and seen the ambulance arrive, she would have believed that it was all her imagination.
Now that Zyran announced the reason they were all gathered, she figured what might have happened. Zyran knew he needed to act quickly when Alvaro became a little better, else the sharks would be gnashing their teeth where they did not sow. And it was exactly what Wilson had come to do, Mila judged from the man's reaction. Zyran has always been a step ahead of everyone, no matter the game, including herself.
