Why did Marinês need to do that transaction? *Spoilers*

My friend,

I guess it was because they wanted to play with the fact that hot girls like welth rich men ! So, Cardozo was a thiny poor guy, with dreams about Marinês ! She dreams about rich men, like all hot girls in and out Brazil ! What's better to conquer besides going to collect the lottery pot, millions of reais (brazilian money), with Marinês herself.

I also thought about it, but then I remembered Cardoso was seen at the bus in a very suspicious beahvior with André, remember?

I thought it was pretty funny, the way they decided it had to be someone that wouldn't screw him, precisely the point that she made quite clear earlier on (albeit in a different context).

kelton,

First, have you ever been in Porto Alegre in Brazil? There are so many gorgeous women there, that they become quite common. The south part of Brazil has some of the most beautiful women in the country (e.g. Giselle Bundchen was born there). Then, it is not unusual that you see guys like Cardoso get the oportunity to talk to them and date them, even though, of course, it's not always that they get anything (as it is the case in this movie).

About your question. Would you ever trust Cardoso all that money?! Andre is too wise to not trust him. Even though Cardoso is a nice guy, since the first time they met, it is easy to see that he is not someone to trust, because he can always leave with the money all for himself (that's just the reality in this movie, quite nobody is trustworth here, not even Andre, although he's the main character). We have to remember that, in the end, these guys don't have any high moral codes.
