The reason Gemma doesn't attack Tiff for doing far worse than John when she made out Angie had been spreading the horrid rumour that David Guest was dead when he wasn't.

That was far worse than what John did putting Darren up.

But Gemma doesn't attack Tiff for it she instead befriends her

while at the same time attacks John every chance she gets

for a far less serious offence,which IMO was wrong,but the intentions behind it were good.

The reason she attacks John and befriends the far worse IMO Tiff

is that she perceives john as a threat to her winning the show,

probably her biggest opponent to winning prob the fave to win,cert one of them because of his huge Eastender's support.

Whereas she doesn't think Tiff is a threat to her winning and she can use Tiff's nature,

IE being stupid and fiery to vi t c h about John for her.
