Ezra Bridger (finds B1's head): Hey, was this a Separatist battle droid?
Captain Rex: Yeah. Little piece of one anyway. This place used to be crawling with 'em. We called 'em clankers.
Zeb Orrelios: Clankers. I like that. How many of these things do you think you blasted?
Captain Rex: I don't know. Thousands. Probably tens of thousands. Never kept count like some of the boys.
Ezra Bridger: They don't look very dangerous.
Captain Rex: Listen, those droids wiped out a lot of Republic troopers. Many of them were my friends.
Kanan Jarrus: Rex has been through a lot. Battles leave scars, some you can't see.
