"There's something about you that makes me a little nervous," Fletcher confesses to Rodgers in an exclusive sneak peek

Jordan Rodgers has already emerged as a front-runner for JoJo Fletcher‘s heart on season 12 of The Bachelorette, but something about him worries Fletcher.

In an exclusive sneak peek at Tuesday’s episode, the Bachelorette tells the 27-year-old former NFL quarterback that she still hasn’t quite figured him out – and that scares her.

“There’s something about you that makes me a little nervous,” confesses Fletcher, 25.

“In a bad way?” he questions her. “Like what?”

“I don’t know if it’s a bad way,” Fletcher, 25, admits, “I just get nervous around you.”

“You said that, but it seemed like a good thing at first,” Rodgers says.

“No, it’s a great thing, because off the bat I was like, just … not skeptical, it’s just smooth and great, and so good so soon,” Fletcher says. “I was like, ‘Is this too good to be true?’ I never expected to meet somebody so quickly and feel this comfortable and excited.”

And Rodgers has some soothing words for JoJo, who was famously blindsided by Ben Higgins on the last season of The Bachelor.

“It’s not an act.”

The Bachelorette airing a special extra episode this week Tuesday at (8 p.m. ET) on ABC.
