I think Juice's suicide or attempt which I think more likely, is going to be the catalyst that starts to draw the club into putting differences aside for a larger problem. Potter's manipulation through Roosevelt is likely to come out, though likely not Potter's ID. Also, if the other cartel is starting to raise trouble the club is likely to push aside its internal trouble to face a bigger threat.
The racism angle may fall away as a red herring- a fear in Juice's head put there by Roosevelt which the club does look past. The other cartel's threat can be something that helps get the club out of running drugs if Romeo's gang can't show they are strong enough to keep out their rivals. Lots of fun with guns in the sun to be had as the season winds up.
