This makes no sense.

They need AT LEAST two hours for all this.

They'll probably start the noms before they go on air.

Armageddon lasts four days. So perhaps the newbies will go in one at a time. It wont all happen in one night. The nominations are on Monday and so is the immediate eviction. The evictee could just go into another "house" and not be evicted at all.

I suppose if it comes to it they could run into BOTS

I really hope a secret house happens

A lot of Monday night's show is often taken up with regular noms. With them not happening on Sunday this week that will free up a bit of time

I don't even if it saves my favourites I'd sooner them go than have yet another secret house
