The ABC dating series' preview clip shows Fletcher crying on the tarmac of an airport hangar as she laments the departure of her latest also-ran.
"I just did not know what this was going to feel like," the real estate developer, 25, says to the camera through tears. "And he just thought I knew! Like, what if that was a mistake. That scares me."
"I, like, miss him," the Bachelor season 20 runner-up continues. "I miss him already."
In the clip, Fletcher is wearing the same blue dress she had on during the rose ceremony that began at the end of last week's episode. That rose ceremony included a dramatic twist right before the Bachelorette picked her final three guys, as Luke pulled her aside to tell her for the first time that he is in love with her. This led Fletcher to cry over the fact that she now didn't know who to cut.
This week's episode features Fletcher heading out with her top three on fantasy-suite dates in Thailand after having met the guys' families during hometowns. Following last week's episode, Jordan Rodgers' older brother Luke gave an interview in which he seemed to accidentally reveal which season 12 guy gets the final rose.
Watch the dramatic scene in the video above.
The Bachelorette airs on ABC Monday and Tuesday at 8 p.m. ET this week.
