I don't really like ranking them before the season starts since 1) it's tough while barely knowing them and 2) I feel like I start getting invested in the characters for little to no reason just from making the ranking lol.
But I do it most of the time anyway so here goes
1. Kaela
2. Derek
3. Hamza (I'm slightly hesitant whether I'll LOVE him but I'm pretty sure I'll at least kind of appreciate a character like him so that's why I'd rank him high like this)
4. Merron
5. Andrew
6. Veronica
7. Paras
8. Rozina
9. William
10. Johnny
11. Ali

[the people I can barely remember what they were like]
12. Olivia
13. Jesse
14. Erica
15. Maddy

16. Mikey
17. Ryan (some slight potential there but idk and I definitely don't know for this forum's taste - then again he could be a complete mess and hilarious to everyone, never know especially with BBCAN)
18. Kirsten (I'm nearly positive I won't like her)
Only not sure about 3 right now. The rest I either hardly remember at all or I liked to some extent.
