Marina's stoic father, Roberto (guest star Cheech Marin), is visiting the family, and Marina can't help but notice that he's been playful and engaged with his grandchildren - something she didn't see growing up. Tom (Topher Grace) is wildly intimidated by Roberto's old-school vibe, but the two of them have a heart-to-heart about the relationships between fathers and families.
