Han Solo showed up on Vader’s Death Star hours after Alderaan was destroyed. On his ship he carried: Vader’s son, Vader’s daughter, Vader’s astromech, his protocol droid he built as a kid, the wookie who saved Ahsoka’s life and literal Obi-Wan Kenobi back from the dead.
Vader must have been like “Who in the Mustafar is that fucker in the vest?”
Then a day later Han sneaks up on the greatest pilot the galaxy has seen in what is essentially a modded 18-wheeler and shoots Vader in the ass!
