Ariel is great; I like her a lot and it seems Zach does too. I'm thinking he might look back at the family visit and realize how very different of a culture she comes from compared to him. And the religion thing may come into play too, for him.
He was really sweatin' and stumbling there for awhile! I liked it. lol
I feel like he has the best rapport and connection with Gabi and Kaity. I like Ariel and think she's extremely poised, beautiful, and highly intelligent, but she is NOT a match for Zach. I'm also not buying that she's a "right reasons" contestant. Not throwing any shade, but I'm a cynical viewer, and I don't think most of them are truly there to find love. She's just so above the fray, like Charlene the opera singer.
