Hahahahahha!! WELL...
Layla was mostly the one at fault... Sam was attracted to Angie and he pulled the moves on Angie a few hours before the right.. Apparently it was the raunchiest kiss BB had ever seen - Sam did leave Angie with a huge hicky on her neck....
AS L had already now claimed Sam, she flew off the handles at Angie.. And as you all know, Angie is not one to take things lying down....
Actually I would say Layla was the antagonist - she kept pushing and pushing Angie until she snapped....
And then after BB intervened she still tried to stalk her down and confront her about it.
Layla showed her history and true colours, Angie then tried to leave the show and spent hours in the diary room......
TBH : Both of them behaved pretty erratically.. But it was only after this fight we started to hear their further stories of fights at clubs in the past etc...
