Marcus was only annoyed because David went to the diary room to choose the most entertaining housemate, and proceeded to say to freddie it should have been him. Markus doesn't like anyone challenging his role of head of house.
Markus could see David was already pretty riled...and then chose that particular moment to throw more accusations which were unfounded at him.....
If it was freddie, then he'd be getting bullied, but because David's not the brightest spark, and talks to lisa then it seems fine for people to behave in such a nasty manner....

I've switched off, I refuse to watch BB anymore....it's not entertaining watching people gang up against others.
