During her time in NXT, Bliss was mostly used as a valet for Buddy Murphy and Wesley Blake. During an appearance on the Not Sam Wrestling Podcast back in 2017, The Goddess revealed that there was a time when she was almost fired from the company."From day one I knew it was my sink or swim moment because in NXT as a good guy my character wasn’t getting over and when I was told about the pairing with Blake & Murphy I knew there had to be a character change. Wednesday night we had TakeOver and I pushed Enzo and helped keep them as champions, I came the next day with new gear and different hair and I knew that if I didn’t run with it, I probably wasn’t going to have a job.”Luckily, Bliss was able to make her storyline with Blake and Murphy work and was then given many more opportunities following her promotion to SmackDown back in 2016.
