CM still had work to complete first and at that stage the McStay family had no idea CM had murdered their family members. JM didn't know the terrible fate that was to come, and at that point JM was probably tired of CM's crap with his sloppy work, complaints etc., and the reason he wanted him out. IMO.Hard to believe Susan and Mike would hire Chase if this was the case. Would have been the perfect time to get rid of him knowing this is what Joey wanted.
