If it is major drama that you are looking for I suggest you go and watch an old episode of BBUK. I just watched the teaser for tonights show and the main highlights were Travis confronting Sam about apologising to Aisha because she is upset and in tears. I mean they promote major drama and yet the best teasers they have is 1 girl crying (I suspect Lawson is crying about something completely different) and a minor confrontation? No yelling or anything?
Sam probably snaps at Aisha during the task when she requests a towel or something and Priya most likely chimes in by calling her selfish or something. With emotions running high inside the house Aisha will run off and cry, Travis will console her before telling Sam to apologise and Priya will tell BB that she will apologise for a minor comment that isn't even that mean.
