At one point in Star Wars: The Force Awakens, Finn and BB-8 are talking. Finn gives BB-8 a thumbs-up. In return, BB-8 extends a little lit welding torch/lighter. I've heard two different understandings of BB-8's gesture:
- It was a thumbs-up, agreeing with Finn.
- It was a middle finger, as BB-8 disagreed with Finn.
Which is the accurate analysis?
