Like Father, Like Son - S4.E6

Alex's estranged father contacts Alex and reluctantly, Alex agrees to have lunch with him. At first, Alex lays into his father about having deserted his family, but eventually they start having a nice conversation. Alex's father, a real ladies' man, even sets him up with an attractive woman sitting at the table next to them at Mario's. When Alex leaves Mario's, Alex's father makes a date with the woman as well. Evidently, both men continue dating the woman, but when Alex learns that his father has double crossed him, he becomes furious and confronts his father. Ultimately, Alex's father lays on the charm enough with Alex that Alex forgives him and they are seen having dinner together.
