OK I didn't read the comics and I don't know what the Wolves are so if everyone could STFU about Wolves that would be lovely
I each of Carol, Rick & Darryl miss the 'outside', hence Rick dry cuddling the wall with a walker, and Darryl's reluctance to clean up and accept a job. They both came around eventually though. Carol on the other hand integrated immediately (obviously as a decoy) to gain the resident's trust. Darryl and Rick believe she just wants to infiltrate them to gain intel.
I think Carol misses the outside so much that she is going to try and sabotage the stability of the community altogether. I don't think she's stupid stealing the chocolate. In fact I think she led that kid on and meant to get caught so she can unleash her rogue plan of sabotaging the stability of the town.
Rick et al will face the tough decision of banishing her again.
PS: Best thing on TV since the old HNIC's.
