Spotthediffference, you write:"Some people might think that Jonas should have gotten rid of Colton, but I disagree."
and
"Tarzan... might just be Colton's perfect goat."
The second statement tells you why Jonas needs to get off of Colton's coat tails. Sooner or later he will need to go goat hunting because Colton is set right now; Tarzan and Alicia are is best chance at the money.
If Jonas lets Colton do all the work, no one will go with him when the time comes. So, yes it's too early to boot Colton but it isn't too early to form a power base of his own. Right now, all Jonas is doing is admiring Colton.
