The two-part story in “The Crossing” and “Retrieval” focuses on the Bad Batch’s first missing without Echo in which the squad looks for Impsium in a mine on a remote planet, getting their ship stolen, becoming temporarily trapped in a mine, and later having to infiltrate and liberate their ship from a Dickensian group working a larger mine for a local tyrant. In terms of larger arcs, the only one notable is Omega‘s (Michelle Ang) abandonment issues, first in Echo’s leaving (and the squad’s minimal reaction) and then to the ship being stolen as well. While a perfectly fine mini-adventure for the group, I don’t know that this really needed to be two episodes.
