Bennett asked Daya to marry him, and wanted to help raise their child and have a life together as a family. But then he saw how Cesar lived - berating one of the kids for not eating french fries - and one flashback to a topless Hollaback Girl dance routine later, he was outta there. We didnt see him again during season 3, but will he come back in season 4? It could be that he was the one who called the DEA on Cesar, not wanting his daughter to be raised in such an environment. Does that mean he could return to raise the child himself? At the very least, he owes Dayanara an explanation and a proper goodbye.
