20 Things You Somehow Missed In The Social Network
6. Sean Parker Reads What He Signs (But Eduardo Doesn't)
Another small moment which says a lot about the characters, now. When Sean takes Mark, Eduardo, and Christy (Brenda Song) to a fancy lunch, he ends up paying for the meal, and is briefly seen wearing his glasses while writing a check.
This seems to suggest that even though he's eating in a familiar place, he sensibly ensures to read anything he puts his signature to.
This appears to foreshadow the fate that's awaiting Eduardo, whose shares are of course famously diluted down from 34% to 0.03% because he didn't do his legal due diligence.
