You were already going to start crying at some point during The Force Awakens. Now it'll be for an actual reason, rather than just loving J.J. Abrams too goddamn much. i09 has the tearjerking story of R2-KT, a pink R2-D2-style astromech droid built to cheer up terminally ill girl Katie Johnson in 2004. While Katie passed away in 2005, her father Albin and the R2 Builders Club got to see her droid on the animated The Clone Wars before wrangling it a cameo in The Force Awakens. Looks like R2-KT will be the droid you are looking for! After which you can bury your face in your popcorn to stifle your sobs. That's why it's the go-to movie food, I assume.
Bleep. Bloop. Bleep!
