Well, then look at it a different way....the PR trip group:
We have AZ, who right after she gets back from PR, leads CA to KC b/c CA called her worried, then Amy leads her to KC. Would she do that if she had just transported the baby to PR? I doubt it.
Next, JPC, who from all accounts doesn't care for KC (according to Amy), would he do that for KC. again doubtful.
Troy- don't know much
And then theres RM, who just got irritated with KC for bringing her current BF TonE to a party while KC was still stringing him along. Would he be the one who took her? Common sense says no.
