When Echo and AZI are on the rooftops, there is a large green billboard in the background which reads "refined coaxium". However, the entire image is flipped horizontally.
Guys this is by far the best Bad batch episode it give us a so dark side series and personally this episode for me was even better than the last ones of the clone Wars S7 it give a so dark star Wars sides and I think they are up to bring a very dark thing to canon about the sake of the clones be prepared the next season is going to be fire am sure also it was the only episode that made be sad and shocked at the same time this episode is amazing and again the most important and serious thing we are getting this season is the sake of the clones and we will finally see what happens to our beloved clones and so few remained alive.
