One way to better deal with the Erlich/Richard situation in episode 4 may have been to have a scene where Big Head and Erlich meet - maybe under the premise that Big Head was looking for advice on how to deal with his situation at Hooli. Then have the meeting work to the reverse effect where Big Head offers up some honest advice or off beat pearl of wisdom that makes Erlich come around to helping Richard. That would have done a couple of things; it would have provided a little more motivation for Erlich's appearance at the Peter Gregory meeting. It would provide some insight as to where Big Head may offer value moving forward. His "unassigned" status at Hooli left him feeling like an almost useless character in this last episode.
