There's theories online that she will play the next love interest of Captain America. She could be playing the grand daughter of the original woman he was in love with in the first movie, because that's who Cap ends up with at some point in the comics.

:)

Special Features - Deleted Scence Section - She is seen as Steve's waitress at a coffee shop outside Stark Towers.

After she gives him his coffee she flirts with him mildly and goes off to another table. Stan Lee makes his normal brief apperance by saying he should ask her out or get her number.

She also recognized him when he took off his mask on the street during the battle.

It's apparent that she will be his love interest in either the next Capt. America Film or Avenger Sequel.

I heard she's supposed to be some big deal in the next one. Like captain America's great grand daughter or something
