Regarding Andi vs Michele. It was a "work." Watch carefully. They really weren't fighting.
But I must admit, no fake fight I've ever seen has convinced more people that it was real. Kudos to the women for accomplishing that.
I don't think I would quite 100% describe Andi-Michelle as fake.
I think the way I would describe it is that they had a gentleman's/(ladies') agreement to refrain from punching each other in the face.
When that happens, the fight becomes an endurance contest, and Andi got gassed first.
