When everyone first introduces themselves in the beginning there is always 5 people who speak a little bit longer then the rest. From each season it was:

 

E1: Jenna, Glen, Sabrina, Christian, Jonna

E2: Calley, Scooter, Christa, Mike, Simone

E3: Bjorn, Tom, Damien, Nicole, Lindi

E4: Julie, Jeszie, Keith, Brook, Chris

E5: Stephanie, Taylor, Alex, Dakota, Martina

E6: Will, Jackie, Cinnamon, Lauren, Leslie

 

I didn't say many patterns except that every single one has atleast 1 person who made atleast top 3 and every single one has one person who went home the first day. And all the odd ones have one of the winners speaking and all the evens don't. but i don't know about E6 for that one.
