In “I'll Be Right Here,” the Bravermans prepare for Kristina's surgery and damn it if the Parenthood team doesn't do an excellent job of recreating the tense and fearful albeit loving atmosphere of a family bracing for a potentially life-altering event. How tense is it? Haddie is ready to bail from her first semester of college (though she'll have her Cornell-emblazoned t-shirts/hats/toothpaste/toilet paper to remind her of campus), and Crosby actually wants to help out.
