1. Bea wasnt even crying, she was just scunching her face up.
2. Her reaction to someone having a calm conversation with her was just too much
3. She spoke as loudly as she could and shouted the word "Freddie", she obviously wanted him to hear.
4. Marcus wasnt shouting at Bea but she cried, Bea was towering over Freddie and patronising him "Why, are you speaking like that?" and calling him a negative little man. Obviously its different.
And when you hear someone speaking badly about you, of course you would get up from bed, especially if the conversation is being had loud enough for the house to hear. What do you expect? The person being bitched about just listening to it and taking it?
