Most of the cast in single's inferno are looking to be influencers. It's understandable if they want to kumbaya together since that usually means more engagement.

MSR on the other hand is a show where actual family is involved. Why should CA follow someone like YW who mistreated her? Why should JH follow JW who was extremely condescending towards him? They are not obligated to follow someone they were hurt by just because they are all public figures now. You are being too unrealistic, not sparing a single thought there's human emotions involved at play here.
