Ooh, this is a great idea! Here goes:
[spoiler]Cry: Sarah's death, Naomi's suicide, the ghost of Jenny singing to baby Lenore, Desmond and Leticia in his cell, Beth's death falling from Widows' Hill, Barnabas and Joshua's farewell.
Scream: I'm with you Alondra.....learning Vicki had been killed at the hands of Jeb instead of living happily ever after was STUPID!!! I mean were we really expect to believe that all the trouble Barnabas went through to go back in time and save her from dying was all for nothing in the long run?
Yell: Barnabas revealing Angelique was the only woman he ever loved!!! Again.....STUPID!!! After all the pain and suffering she put him through he decides she was his one true love.....YEAH RIGHT!!!!
Laugh: Quentin's one-liners in early 1897, Judith dragging Edward out of bed in the middle of the night to tell him she's moving into Grandmamama Edith's old room, 1795 Trask being tormented by Barnabas' ring-wearing hand while a bewildered Nathan (who sees and hears nothing) looks at Trask like he's crazy.[/spoiler]
Cuss the writers: i.e. Scream and Yell
