The look of the local man being bullied by the Stormtrooper Captain in the opening scene is based on early concept art for Han Solo by Ralph McQuarrie.
Second of four preview shorts that introduce the Rebels characters before the series premiere. This short introduces Sabine Wren.
According to the companion book "Sabine - My Rebel Sketchbook" Sabine uses the following fuels to create her paint bombs: rubidium (purple); calcium (orange); barium (green); sodium (yellow); strontium (red); iron (gold); copper (blue) and beryllium (white).
Sabine's call sign is Spectre-5. This indicates she joined the group after Zeb (Spectre-4) and was the last to join before Ezra, who gets the call sign Spectre-6 at the start of the series. The tie-in book "Sabine - My Rebel Sketchbook" (by Daniel Wallace) reveals that Sabine was recruited by Kanan, although no further details are given.
