I absolutely love the continuing joke of “Fire, Water, Earth” brought to life in Burrow’s End. It’s such a good bit, one that transcends specific series and instead centers itself on a group of friends.
That being said, I’ve seen multiple people begin to predict who is gonna be air. I figured I’d throw my hat into the ring.
First of all, though I love him as a DM, it’s not gonna be Murph. This joke in particular centers around people who are intertwined with both CR and D20. And, as much as I love him, Murph is not that guy. I have no doubt that he’s at least friendly with the Critical Role cast but it’s obvious that he’s closer with Brennan then he is with Aabria or Matt.
So if I had to make a guess, it probably be Spencer. Not only is he involved in CR related content (Candela), he is good friends with both Brennan and Aabria. I’m fairly certain that he was part of a private campaign that involved Matt, Brennan and Aabria.
Something else that I’ll throw out, is that the next time we see the joke, it will probably be during an new season of EXU. I have no insight on when the next campaign of EXU will come out, but I have a fairly strong suspicion that Spencer would be the one Dming it. And that is where we will find our missing joke.
Speaking of, this is off topic. But if anyone feels like drawing Brennan, Matt and Aabria as Fire, Water and Earth Gensai respectively, I will love you forever. Please.
Lil indulgent headcanon that Twilight's still around but she disguises herself as a traveling earth pony librarian named Velvet Starshine (Argyle's mommy hehe). Her little necklace is charmed and disguises her appearance. She never ages so she moves towns constantly and never gets too attached to anypony no more.
