Is Bryan Abasolo too good to be true? Rachel Lindsay has expressed some doubts about The Bachelorette front-runner, and her family shares those concerns.

During last week's episode, Rachel's parents and sister met with Rachel's final three guys. And the family opens wondered if Bryan was too slick. They questioned how quickly he fell in love with Rachel. And sister Constance, in particular, noted that Bryan always seemed to have the perfect answer to every question.

And it's not just Rachel's family that feels this way. Bryan's main rival, Peter Kraus, has also questioned the doctor's true intentions. During last week's episode, Peter told Eric Bigger, "We already know, I've made it very clear that I'm not the biggest fan of Bryan. He's got his confident Miami swagger. But in Miami there's a lot of fake boobs, fake asses, and fake cheeks, so what that swagger is, I don't know." 

Even Rachel herself wondered about Bryan's sincerity at first. But by the time she introduced him to her family, she no longer had any doubts about him. She even reassured Constance that Bryan isn't too good to be true.

"It was just important to me to let her know that, 'Listen, I'm not an idiot. I saw the same thing that you saw and you should know that I worked my way through it,'" Rachel told ABC News. "He's here because he's proven to me that he is who he says he is, so I didn't think that in a hometown [date] he could do that for her, but I wanted her to know that, 'I see your concerns. I saw them too.'"
