The two kids ask SEN his name. He asks them for theirs, and one whispers to the other he doesn't have to tell him. One responds that it's okay, and they tell him their names, and they all shake hands. It's less than a minute of footage not in any officially released home video version. It miraculously turned up in the battered full frame 16mm print I now have.

I've speculated in the past Lucas trimmed the scene because it makes SEN a slightly more sympathetic character.

JEDIT:And my question has been answered. ;)
