What went down on On Braxton Family Values Season 4 Episode 9?

Towanda, Traci and Trina did their best to calm Tamar's nerves before she took the stage in Atlanta and then they did one better: they surprised their sister on stage.

But Tamar was thrown off-guard by this gesture and the surprise totally backfired. OOPS!

Elsewhere, Toni and Dr. Sherry attempted to help the ladies work it out, but they only ended up fighting more. Will they ever get back on the same page?
