Some spoilers...
* Phyllis fires Bette due to Jodi's claim about Bette threatening to fire her and then, after firing Bette, she comes onto her and tries to kiss her. It's a really, really funny scene. This then leaves Bette jobless, which is a big problem because Bette and Tina are adding a second floor to their home for the new baby that they are adopting, a boy that a teen mother of two by the name of Marcie is giving birth to and decided on Bette and Tina as the adoptive parents, although her parents are extremely homophobic and do not accept Bette and Tina's lifestyle, and so they don't want Bette and Tina as the adoptive parents. The baby boy's father is African American, also, that which Marcie confided in Bette and Tina about, although Marcie's parents are unaware of this.
* Bette becomes Kelly Wentworth's partner at the KW Gallery. During the gallery opening, Tina has to go to N.Y. for work purposes and so Bette is at the gallery opening with the girls, but when she returns home Kelly stops by and surprises her, inviting herself in with a bottle of champagne. Kelly comes onto Bette and Bette pushes her away, which causes Kelly to spill her drink. Bette kneels to pick up the spill and as this is happening, Jenny walks by Bette and Tina's front yard, hence seeing Bette kneeling and Kelly standing in front of Bette. Jenny then takes a picture of this, believing that what she is seeing is actually Bette going down on Kelly Wentworth, when in fact Bette had just pushed Kelly away and knelt to pick up the spill.
* Carmen and Marina do come back... why, that I don't know just yet. I suspect that it's for Jenny's wake.
