Luis

Luis finds out that Marly bought a pregnancy test and goes through the roof. He's mad that no-paying-job-in-sight Greg got his daughter pregnant, but Greg is excited - he's always wanted a little ""Quarter- Rican."" Luis finally changes Greg's mind when he tells him a baby would mean the end of Greg's art career. As Greg tells Marly he may not be ready for fatherhood, Isabella enters and asks Marly if she ""ran that errand at the pharmacy"" for her and Luis could not be more shocked. Luis assumes that the baby is his, which everyone assumes is impossible until Luis and Isabella reveal that they are sleeping together.
