S12·E16 Fire Walk

Tina is running her loud mouth off about her dislike of Mary Beth again. Tina admits that she personally is self-conscious, but adds that she doesn't try and be fake or something she's not, implying that's what Mary Beth does. Dave is finally wising up to the fact that Tina is trying to make Mary Beth jealous. Tina suggested the two shower, but he knows this would ""cause too many damn problems"" in his life. Not backing down, Tina continues to make overt passes at Dave back in the RV. Mary Beth is not fazed by Tina's actions and says she is childish and immature and she's not fooled by her games.

Tina and Mary Beth rehash the fated dinners with the ever-popular Octave and they begin to fight. The claws start to come out and Mary Beth cuts Tina off and tells her she doesn't care what she thinks. Mary Beth is confused because she says she hasn't done anything to personally offend Tina.
