The reason Robyn was on the ATV!
So we’ve all seen the preview of Robyn getting thrown off the ATV. Lots of us questioned why she would ride in the first place, considering what happened with Dayton. Also, with her anxiety of outdoor activities.
Well, I think I have the answer! She’s still trying to prove to Kody that she’s the best/most fun wife.
In season 18, we see Janelle and Christine going to Christine’s brother from another mother’s house and they go ride ATVs and go hiking. We also see David and Christine riding that 4-seater side by side in the Utah mountains.
