Kacie Stuns 'Bachelor' Ben in Switzerland

Tonight's episode of The Bachelor has Ben Flajnik heading to Switzerland for exotic dates with the three remaining contestants vying for his love. But the show takes an unexpected twist when castoff Kacie Boguskie surprises Ben at his hotel.

These new clips show Kacie's apparent apprehension as she approaches and knocks on the hotel door, as well as Ben's jaw-dropping reaction to his surprise visitor.

In another segment from the show, we see Ben and Nicki Sterling taking a breathtaking helicopter ride above the snow-covered Swiss Alps until they are literally dropped high on a mountaintop for a romantic embrace.
