Jovani did all the pieces that he could do while driving. He had contacted Alonso to get a trace of the vehicle that Zane had been in. If one of their phones was up, he would be able to find out where exactly they were at.
He also contacted a few of his other men to put handle the issue on hold until he got back. If the two were connected, he knew that he wasn't going to be the only one who wanted to get a piece of those men. Lena would want to have a say in what happened to them as well.
Jovani also made sure to contact his younger cousin and Romeo to make sure that they didn't allow the princess to leave the house. He didn't know if she was aware of exactly what was going on but knew for a fact that she wouldn't want to sit still if she did.
