This is more if they had a fourth season and I was given the power (25 characters in my mind but I'll only post 22 for reasons bellow):

22. Duncan (he's been in the final four two times and I believe if you been in the final four once you don't do that again till three seasons later plus unless he starts becoming nicer to Harold and loss his jerk ways I will continue to dislike him)

21. Courtney (hate her the most of all characters and like Duncan became to focus on)

20. (Owen (similar reasons as Duncan but I like him and I love the Izzy/Owen couple so he goes for third out)

19. Geoff (his jerk actions and constant make out has me not liking him so much so he gone unless character changes big time)

18. Leshawna (I like her and I love the couple of Harold/Leshawna but I want characters who didn't get much character development, relationships time, or overall screen time to last longer)

17. Gwen (similar to Leshawna)

16. Justin (loses his powers on all the females but at least have him make one true friend as I found some pity for him in the episode he left)

15. Heather (hopefully she will be changing her ways slowly to a more protagonist character)

14. Trent (he went middle ground in TDI and out fairly quickly in TDA so I want him to stay long enough to handle the Gwen factor and perhaps fix his 9 obsession)

13. Lindsay (I like her but she lasted well in TDI and TDA so once again I'm letting her go here so the other lessor characters will have time to shine)

12. Bridgette (I like her so I want her separated from Geoff so no kissing interruption will happen)

11. Katie (Long enough for some screen time and some independent action away from Sadie)

10. Tyler (I'm neutral about him but I want him to last longer to handle the relationship he has with Lindsay, a reason he wants to be a good jock, find one sport he's good at: maybe Curling , and screen time)

team merger ends

9. Harold (my fave character but he lasted long in the last season and others still need more screen time and character development plus it would add to the 13 bad luck factor)

8. Beth (I didn't think she was given much plot or screen time compare to many of the others even though she was in the final two plus she started to rise once separated from Lindsey and at the end so I want her to last longer so a second chance for plot and character development can concur but like I wrote before if you made it to the final four before you won't be doing so again until much time has gone by)

7. Sadie (like when Beth was separated from Lindsey I hope her second separation will be different and more productive. Smarter of the two gals I choice her to last longer and make it count more with good plot)
6. Ezekiel (being the first one out and no lines in TDA I want him to last long and have character development and plot, respects gals seeing their strengths and calls his father who taught him the wrong sexist lessons off)

5. Izzy (popular character and very funny but has lasted long in both and has come back twice so I don't think she should win)

4. DJ (very nice guy with a big heart who's kindness should be his rewarded by staying for a long time till the final four)

3. Noah (fan favorite and funny with more time to shine now)

2 or 1 (fan voting). Eva (Lessor characters getting more air time and plot is a major factor of my ideas of the show plus with Cody and Eva in the final two it will be a David vs Goliath story. Possible relationship signs with: Noah, Ezekiel, or DJ)

2 or 1 (fan voting but cannon 1). Cody (Likable and not in second season Cody makes it to the final two with finally a girlfriend)

Alejandro and Sierra as I haven't seen the characters in action so don't know where to put them in the list (making it 24 characters) plus maybe adding Brady to the mix so we see Beth/Brady couple and how it started and works (a loving couple with strong bonds beyond looks) plus his own independent character plot and interactions (making it 25)
