I also don't "get" Caleb, because I don't for a moment believe Colton is different in real life.
If Colton is banned from the reunion show I wonder if Caleb will boycott it. (On top of the possibility that Tina and Katie might not be there either.)
Colton ultra messed up. He and Caleb could have had a terrific all-expenses-paid vacation together in paradise except that one is at Ponderosa and one at Loser Lodge.
