I watched, and felt bad for Tamar. Seems to me Towanda is really jealous, I mean the attitude she was throwing at the press conference? Not to mention the mocking of Tamar while in Italy... Wow... And at the end with the Tamar/Toni conversation, I believe Tamar that she has no beef with anybody, and that she has been tryna reach out. Toni probably should have went to Towanda instead, and/or the other sisters.
If the girls really wanted to do an all sister get away, then it should have been planned, I mean to spontaneously spring it on Tamar, knowing full and well she has a bunch of work and promo to do wasn't fair.
