Caleb's medical evacuation is really upsetting the whole natural course of the show.
As I bet all three of the med-evacs will.

I imagine that this season will not run similarly to any previous season's confessional counts and cues.
Yes, there will always be a difference between journey players and those with real potential, but... I also think that some of our "potentials" aren't getting the attention that some of our med-evac characters are.
For instance; Caleb, Tai and Jason. All are strong players who are not only finding idols but are influencing peoples decisions. And outside of an alternate numbers situation (swap) they seem to be quite safe in their current scenarios.
BUT...(pure speculation follows)
On Brawn, what happens to Alecia once Jason is gone due to a med-evac? (Her way looks a lot clearer for a long time)
Or on beauty, losing both Tai and Caleb due to med-evacs gives Nick a lot more time to get with a non-beauty and last even longer.
IOW, these med-evacs are good cover for those whom ACTUALLY make it to the end and will definitely alter how the show SHOULD turn out.
