Double Drabble: An Understanding (Star Wars, Gen)

Title: An Understanding
Fandom: Star Wars
Characters: Artoo, Chopper, Zeb, Rex, Wedge, Luke
Disclaimer: I own nothing to do with Star Wars. It's not my toy box and I'm merely playing. The part about Artoo getting Chewbacca to give him a weapons upgrade is from the Star Wars Comic #36.
Rating: PG-13
Summary: Artoo and Chopper aren't friends.
A/N: Written for the drabble_zone prompt: long lost friend.
Warning: Rex has a panic attack. References Chopper's PTSD when it comes to Y-wings. Artoo stress about no one understanding why he put himself in lower power mode. Violence (R2 zaps Zeb and Chopper rams into R2 at different points in this story).
