"I'm Luke Skywalker and I'm here to rescue you."

The episode is even called "The Rescue". It would have been so badass! I'm starting the latest episode of Mindalorian now, forgive me if this gets covered.

I fully expected him to at least a crack a smile!

Though I guess that might have made the simulacrum literally crack. Oh well.
