It was the second death of a Challenge cast member in November.
Ryan's girlfriend, Makenzie Jauer, then shared this heartbreaking post on Instagram, calling Ryan her "sweet angel."
I love you Ryan Knight. I am heartbroken, confused, hurt and most of all mad. The pain I am feeling now will never go away. You mean more to me than you will ever know & I never thought that I would spend a day without you. Every second with you was full of love and laughter. You were the brightest light in every room. You taught me not to care about what other people think and you made me understand that being myself was okay. Thank you for being inappropriate at the worst of times and making me laugh until I cried. Thank you for loving me unconditionally even though I snored and drooled on you in my sleep. You had the sweetest soul and I will never forget that. I always called you "my sweet angel" and now you truly are. Love you forever, MEK
