Again, I'll agree with others who've speculated that Christy's not the type to hold anger for very long. She lets it out and there it goes.
Some other considerations:
1) Would Christy, a graduate from the liberal arts school Gallaudet, vote for someone who claims to have emulated Colin Powell?
2) As a sensitive woman who values human relationships, weren't Christy's questions really about Matt and Jenna's connections to her? (What did you think when you realized I was deaf, Matt? Why did you play the "beauty handicap" card, Jenna?) Matt and Jenna cleared themselves of possible offenses and then Christy was free to choose whom she felt played the best.
3) As fluff and others have indicated, the jury members talked. Deena and Rob are persuasive, no?
For what it's worth, I'm not disappointed in anyone.
