Although, he wanted to share this good news with everyone else, he didn't do it now as it would be overwhelming and he had to focus on safely bringing back Lucas first.
So, for the first time, he didn't even share this truth with David.
Chance somehow found a way to contact Giuseppe.
Lucas was shocked when Chance contacted him but he was glad as he knew only Chance was capable enough to get him out of this place.
Then they made a plan to take down the Berlusconi gang but unknown to them they came across this new problem.
Marco, Flavio's right-hand bodyguard, got to know Chance is digging about them so he warned Flavio about it ruining Chance and Lucas' plan.
Flavio decided to kidnap the three women to trap Chance.
This decision was made immediately and therefore, Lucas did not get an opportunity to warn Chance about it.
