Start from the beginning.
1 - Flint walks to the back of the vehicle, passing by row upon row of passengers, all of whom are gawking after him in a combination of surprise, disgust, and many feelings in between. The passengers are a mix of humans of aliens of all varieties - humanoids, insect creatures, blobs, beings of gas, and all manner of other colourful creatures.
2 - Flint sits down near the back of the vehicle next to Squirt, a nervous water-based alien whose watery insides appear to be held together by some type of membrane. Despite this, he has something approaching a face and looks nervous (maybe he's sweating?).
SQUIRT: Why would you come back?
3 - On Squirt and Flint. Squirt tries to talk some sense into Flint, while Flint looks out the window in an absent-minded fashion.
SQUIRT: You can't win this.
4 - On an anthropomorphic Snakeman-type alien near the front of the vehicle. He looks completely furious, narrowing his eyes and flicking his tongue out menacingly (can one flick a tongue menacingly?). Some cronies may be nearby, but the Snakeman is the focus - maybe he's getting some type of hand-to-hand weapon ready.
FLINT (tailless): Only one way to find out.
