Ep.04 Jack is back in the City, and knows nothing about Paradise nor neo-Zootism. His is set upon by a mob and must run for his life. A convenient dumpster is a good place to hide. And Gel had thought so too...
Jack rounds the corner, and so out of view of the pursuing mob. The wooden crate is a good jumping off point ... In the blink of an eye Jack lowers his right hand to get a good grip on the far edge while at the same time switching his left hand also to the far edge. He now lowers the rest of himself into the dumpster...
And so Jack lowers himself in....

But how did he instantaneously move his hands from there to here? His front facing outside to his back facing outside? And that cardboard with "DO NOT S..." Where is that in the top pictures?

Inside, and well concealed, Jack finds Gel.
