Marie is fiercely loyal, so she tries to protect everyone. Unfortunately, this sometimes means she doesn't look out for herself first, and often plays a scattered, emotional game as a result.
These two have been at each other's throats for years, starting on The Challenge: Dirty 30 when Marie actively campaigned against Cara Maria, seeing her as one of her biggest threats. On The Challenge: Vendettas, they tried but failed to work together, and things didn't improve when Cara Maria also stole Kyle away from Marie. Not content to keep it on the show, they continued their bitter rivalry on Twitter, where they traded jabs continuously. Now these two mortal enemies are going to have to figure out how to work together, but don't expect it to be smooth.
