'Bachelor in Paradise' ramps up drama with sister twist

Now we all know "Bachelor in Paradise" loves drama, and on tonight's season premiere we got double the trouble. Surprise.

Ashley I. brought her younger sister Lauren to paradise and everyone was shocked.

At first the other girls were upset because they didn't think it was fair Lauren got to be in paradise without going through a Bachelor season. And then the twist:

"The sisters are a packaged deal. So if one person gets a rose the other person stays," Carly explained.

And Bachelor fans on Twitter felt the same way, saying they didn't know why Lauren was on the show.

News of the sister act broke before the premiere, giving media outlets enough time to find out who Lauren is.

A writer for Bustle concluded, "I think it's safe to say her sense of humor combined with her fierce protectiveness of her sister is going to make for some great TV."

Some great TV indeed. But "Bachelor in Paradise" isn't the only show this summer with a sister twist.

Big Brother had twin sisters flip flopping throughout this season, which for BuddyTV was "terribly disappointing."

But it looks like the sisters on "Bachelor in Paradise" won't disappoint. From just the first episode a writer for People pointed out, "The gene for drama runs in the family."

And a writer for Zap2it says the sisters "form a dynamic duo that must stick around on this season. Must."

To find out if the sisters stick around, watch "Bachelor in Paradise" Monday nights on ABC.
