This article is going to assume that WWE are booking a Firefly Fun House Match as the grand WrestleMania 37 payoff to the Randy Orton/Fiend feud that has been going on since November.
No, not "assume", that's not it.
Hope, perhaps. Expect, absolutely. Need, definitely. This article (and indeed your writer) hopes, expects and needs the Firefly Fun House Match to be the grand payoff to the Randy Orton/Fiend feud that has been going on since November, if only because this is a Randy Orton/Fiend feud that's been going on since November.
The pair wrestled on Monday Night Raw. They fought in the fire and flames of the Firefly Inferno at TLC. They battled a lot between 2016 and 2017 in contests that involved projections of insects in the ring, filthy kitchens, teleportation and a crucix - an object that still brings up the red squiggly line when you type it. Wyatt fans might well consider that part of its mythology - "the crucix is so unstable that even the correction underneath can't think straight, it's #longtermstorytelling actually" - but then without that amount of head canon how on this earth or the next one can any of this stuff work?
A Firefly Fun House Match means it never really needed too. Oh holy sh*t Wyatt's literally lying there on fire, oh holy sh*t there's black goo everywhere, oh holy sh*t Alexa Bliss can now bring people back from the dead in her role as infantilised former sex object. Imagine if all of this was wrapped with "Oh holy sh*t the Firefly Fun House Match was f*cking awesome and this feud never needed to be attached to any form of reality after all".
That was certainly how it felt by the end of WrestleMania 36.
