Warning: Spoilers for “The Mandalorian” season 2’s fifth episode, ‘The Jedi’

Some of the droids seen in the latest episode of “The Mandalorian” wore a symbol on their helmets that ties into deeper “Star Wars” lore.

What happened:

The fifth episode of the season — titled “The Jedi” — featured Din Djarin (Pedro Pascal) and Grogu (Baby Yoda) teaming up with Ahsoka Tano (Rosario Dawson) to take down the leader of the city Calodan on the planet Corvus.

The leader — Morgan Elsbeth — had a slew of droids at her disposal to use against Mando and the crew.

Internet sleuths discovered the droids had a symbol on their helmet that looked like a mask. It turns out it’s the same symbol as the Seventh Fleet — the fleet led by Admiral Thrawn, a major villain in the “Star Wars” universe.

This moment makes sense since we see Tano ask Elsbeth about Admiral Thrawn, wondering about his whereabouts. That moment has significance, too. Since Tano is on the hunt for Thrawn, it suggests she’s still looking for Ezra Bridger, the star of “Star Wars Rebels” who disappeared with Admiral Thrawn at the end of the series. It was hinted at that Ahsoka and Sabine Wren (another character from “Rebels”) would go on a search for Ezra.

Thrawn is considered one of the biggest “Star Wars” villains in history. He was originally added to the books after “Return of the Jedi” before being added to the canon after Disney bought Lucasfilm. Prequel books about him reveal a complicated figure, who has put an emphasis on logical and military strategy over anything else.
