In the press release for this episode, however, Karla Souza was included in the main cast list. Timothy Hutton was not.
Karla Souza didn't appear in the episode, nor was she credited.
The flashforward to Annalise's Funeral doesn’t contain any kind of indication of when the funeral takes place. Other flashforwards in previous seasons have always included countdown to the actual event so to speak. For example, the flashforward at the end of "I'm Going Away" takes place three months after the events in the episode. No such information was given in "Say Goodbye".
At Annalise's Apartment, Annalise has Michaela and the others take their anger out on a cushion just as she did in rehab by beating it with a fire poker. Annalise tells Michaela to let go of Laurel as she can take care of herself in order to allow Michaela to move on. "Beat her away! Say goodbye."
