Yeah Jason was only ever a leader of 3 people at most, and you can hardly say he controlled Victor really. Vanessa maybe but the rest seemed at odds with him/Victor on more than one occasion.

I'd say Michelle ahead of Nadia though considering she obviously had Stuart under the thumb in addition to friendships with Marco, Emma, Shell and Victor.

I don't get how it could have been Nadia or Jason, Dan literally was friends with everyone and he and Shell ran the house

Yes. Dan was the peacemaker for a lot of them.

BB7 had a couple, Grace was one but Lea and Richard both became alphas at different points.

Yes Dan was the peacemaker and definitely the spokesman of the group. But Jason was the Alpha, it was just that he tolerated Dan and allowed Dan to be the groups spokesperson.

As for Lea being alpha, you have to be kidding, she was a mess.

Big brother 7 is probably the greatest series for these kind of house dynamics.

First off Richard took it upon himself to be the leader, but after he had that argument with Imogen, Sezer stepped in and challenged him, and Richard was reduced to tears, and his reign was over. But then the public voted Sezer out a few days later, and Richard regained the crown as the King.

But the female leader was Grace who was only twenty years old, but was the mother/Queen of the house, she had to comfort people like Nicky who was actually four years older than her. But after a quiet first few days in there, Aisleyne decided to make her move to challenge for Queen, and when Grace was evicted, Aisleyne became Queen of the house.

There's a real interesting moment just before Sezer was evicted, when Richard is planning to get back his reign over Sezer, and he tells Aisleyne to become the leader of the opposition and he will back her.

Watch from about 11.20 to about 12.20
This is the episode where Sezer was evicted

Bump now BB18 is over.

I'd say Chanelle was the alpha of the house in BB18.
