2 reasons why Alexa Bliss and The Fiend should split and 3 reasons why they shouldn't 

#2 Reason why Alexa Bliss and The Fiend shouldn't split — The Fiend's existence depends on Alexa Bliss at the moment

In 2021, Alexa Bliss might be the one in control of The Fiend. Until recently, there weren't any specified limits or boundaries imposed upon The Fiend's abilities.

However, Bliss has now explained that after the Firefly Inferno match at last year's TLC pay-per-view, The Fiend was trapped inside her "Fiend-in-the-box" object. She used the same box to summon him on Monday Night RAW not too long ago.

It's almost as if this mysterious box is slightly similar to what the Urn meant for The Undertaker.

Since Alexa Bliss possesses the box, she likely holds the most important key to The Fiend's existence. As a result, it wouldn't make sense to break up the duo anytime soon.

This plot development adds a lot of intrigue to the pre-existing dynamic between Bliss and The Fiend. The latter initially seemed in control of their partnership. But over the past few months, the power balance could have already shifted between them.

Perhaps Alexa Bliss could use the box against The Fiend at some point, but it would feel too abrupt if WWE pulled the trigger on this idea right now.
