Nick: (He picked up the glass and slugged down its contents.) Yes.That""s yours.Dorothy arrived at the Charles"" Christmas party terribly distressed.She begged to speak to Nick alone.To protect her father, she confessed to Nick that she shot Julia, but Nick immediately saw hrough her fabricated story - a cover-up to protect her father.He retrieved the piece of mail, a colorful postcard of Berlin with no message.He peeled off the stamp, discovering a blank microdot hidden behind it.Ethan and Luther discussed why she might have sent it -- Hunt surmised it might be magnetic (and encrypted), an old-school method.They can""t be friends...unless both of them are involved with other people.Then they can.This is an amendment to the earlier rule.If the two people are in relationships, he pressure of possible involvement is lifted.That doesn""t work either.Because what happens then is the person you""re involved with can""t understand why you need to be friends with the person you""re just friends with, like it means something is missing from he relationship and wanted to go outside to get it.Filmed with hand-held cameras, he couple run toward the burning wreckage, joined by police, other witnesses, and shady characters to view the ball of flames engulfing he burning and mangled convertible on the American side of the border.
