#3 To eventually turn on Nikki Cross
Some people and wrestlers like to play games with others. There's literally a comic book character in the Marvel Universe who does this called the Grandmaster. He constantly pits heroes against villains and heroes against heroes in order to both win bets or to prove a point. While Bliss is a Goddess in name, she isn't an actual cosmic entity.
But that doesn't mean she doesn't get some sort of sick pleasure from toying with people. Maybe since things changed a lot on Raw after the Superstar Shakeup, she needs a new challenge since she's out of the Raw Title picture. Nikki Cross is the new kid on the show and she wants to toy with her and teach her a hard lesson.

Or maybe she's just evil. Bliss has always been a heel and done everything in order to get whatever she wants. Cross might be a means to an end and once she is done with Cross, she (Bliss) will toss her to the side. It wouldn't be the first time she's led a friend on (Nia Jax) and it probably won't be the last time either.
