'The Bachelor' sneak peek: Cassie's father questions her relationship with Colton

It's down to the final four and this week is hometown dates on "The Bachelor."

In this sneak peek, Cassie brings Colton home to meet her family and her father isn't too thrilled she's thinking about marriage so soon.

First, he notices how affectionate he's being with his daughter and that's never good when meeting your possible father-in-law.

"I don't know if that's what he does with all the girls he goes out with and meetings with parents," Cassie's father asks.

Later, he questions his daughter, especially about possibly becoming engaged only after a few weeks.

"It's just something you don't jump into," he says.

"If I'm going to accept a proposal, it's gonna be because I'm sure," she says.

"How can you be sure after that short of time?" he says. "You're 23, you have a life ahead of you."
