The Duel of the Fates
So let’s talk about this fight for a moment…
This was the first time in nearly 1,000 years that a Jedi had seen, let alone fought, a Sith.
Not a Dark Jedi, a Sith.
Up to this moment (or arguably the skirmish on Tatooine), the Jedi had believed the Sith were wiped out a millennium ago.
This was the Sith’s big reveal, more or less announcing to the Jedi Order, "We’re here. We’ve always been here. We’re coming for you."
I think the sudden realization of the situation they’re in shows very clearly in both Obi-wan and Qui-gon’s expressions.
They know they’re dealing with something far beyond anything they, or any Jedi in the past thousand years, have faced up to this point.
And that’s just a little bit scary, don’t you think?
