What happened to Tup is one of the saddest stories in TCW. So naturally I wanted to dive in to it a bit! The dynamic between Fives and Tup is also really heartbreaking, and it showcases a lot of Fives’ quirks and tendencies for physical expression.
I will cover some of what happened in the inhibitor chip arc, so be forewarned.
At first, Fives is rough with Tup, as he usually is when messing with his brothers
but he keeps an eye on Tup throughout the next battle.
Fives reacts to Tup aiming his blaster
and tries to prevent it from happening
but of course, he’s too late (notice how Fives is the only trooper to DROP EVERYTHING in the middle of the battle to restrain Tup).
Despite Tup executing a Jedi in cold-blood, Fives isn’t frustrated like Rex or flummoxed like Kix – he’s terrified for his brother.
