House of the Dragons made a Muppets reference you almost definitely missed
One of the challenges of adapting Fire & Blood is that the Game of Thrones prequel is more history book than novel, lacking much of the quirky character moments and meta fantasy jokes that are sprinkled throughout the A Song of Ice and Fire series.
In fact, the name Grover Tully feels rather in line with other Westeros names like Aegon, Larys, or Viserys.
(If anything, it’s characters named Jason that immediately stand out.).
Ser Elmo then has two children of his own, Kermit and Oscar.
Martin leans further into the extended Sesame Street reference in Fire & Blood when describing how “green” Kermit is as a soldier and Oscar’s “prickly” personality.
So while the mention of Ser Grover Tully is a pristine Muppets Easter egg, it’s also possible that the reference is sowing the seeds for the eventual on-screen introduction of the entire Muppet Tully family.
