Mexican Guy: Anything for Salinas.
Selena Quintanilla: I may not be street wise and all that, but at least I know not to be that dumb.
Abraham: We have to be more Mexican than the Mexicans and more American than the Americans, both at the same time! It's exhausting.
Abraham: No female has ever made it and now you're number one. You cracked the Tejano market wide open. You walked into Mexico and they don't even accept Mexican-Americans and they love you, and now?
Selena Quintanilla: And now... gringos. Disney World.
Abraham: You remember?
Selena Quintanilla: Uh-huh.
Abraham: And all the barriers that have stopped people before... and you went through them like they didn't exist. Maybe for you they don't exist. I love you, and I'm very proud of you.
Abraham Quintanilla: You were out there wearing a bra.
Selena Quintanilla: It's not a bra.
Abraham Quintanilla: It's a bra with little sprinkly things on it.
Answer: Looking at the credits on IMDB it does show that Panchito Gomez played young Abraham in Selena as well as the role in Tuff Turf. Given that 12 years had passed between the two movies, it's possible that Panchito had gotten older and didn't look like he was when he was 22 compared to mid 30s.
