According to this website, in episode 4, "the Bachelorette arrives in New York City before the men to participate in a fun, fabulous make-over and photo shoot for InStyle. Kasey and Ali share a special day in New York, beginning with a panoramic helicopter tour of the city and ending with a giddy late night date at the Museum of Natural History. Seven eager bachelors hit the bright lights of Broadway, as they audition on stage at the hit musical "The Lion King," to not only win alone time with Ali but to have the extraordinary opportunity to perform with her that night in the Tony Award-winning show. Then Ali, despite falling ill, and Chris L. still manage to have a romantic night topped off by a special performance by Bachelorette favorite singer-songwriter Joshua Radin and the Harlem Boys Choir. But Kasey slips out of the men's New York suite, mysteriously returning with a bandage on his wrist. What happened to him? All is revealed at the stressful rose ceremony where two men will need to leave.
Ali has a great time trading in her casual California style for sexy, date night outfits with the help of InStyle during her makeover and photo shoot. The looks will be featured in the magazine's July issue (on sale June 18). In the meanwhile, Kasey is tapped for a one-on-one date and vows to "guard and protect Ali's heart" and return with a rose. A sweeping helicopter tour over Manhattan takes the couple to Liberty Island, where they have a romantic sunset picnic. Then the Bachelorette takes Kasey for a night time exploration of the Museum of Natural History by flashlight, as they enjoy having the empty museum all to themselves. But when they settle down for some serious talk, will Ali be satisfied with Kasey's answers?"
