Anakin had never, ever imagined that ten years ago, he, his master, and those Jedi Masters had been captured on this very planet and nearly shot to death in a hail of gunfire! And now, ten years later, after growing up and making the incredible leap from a slave boy on Tatooine to a handsome, wealthy Jedi Knight, he had once again been captured here by the Separatists. Together with Padmé and Obi-Wan, who was just as unlucky and had been captured here twice, he had been hurriedly tried by the Geonosians on the ridiculous charge of "espionage," among other things, and sentenced to death.
But fortunately, he wasn't too worried just yet...
It wasn't that Anakin wasn't afraid to die. It was because he'd calculated the timing several times and arrived at a result that was slightly dangerous for them, but also favorable? Anyway, at least he felt that what was happening was still within the bounds of what he could accept.
The damn Geonosians hadn't simply dragged the three of them out to be target practice for the battle droids. Instead, they had thoughtfully arranged a "farewell" ceremony, apparently intending to let countless Geonosians witness their deaths in this huge, ancient arena.
And that was Anakin's chance!
So he cooperated quite willingly as the Geonosians carried him to a hover transport and paraded him around the enormous arena. After the procession ended, they chained him to one of the four stone pillars in the middle of the arena, all the while cheering and howling with enthusiasm.
Only after the insect-like Geonosians had tied him up and flown away did he realize that Padmé and Obi-Wan, who had arrived before him, had already been bound to their pillars for some time.
"Padmé!"
"Good, you don't have to be afraid.
