You can always trace it further than that. Clem wouldn't have trusted him if he had never began talking to her in the first place. Or perhaps it was Carley/Doug's fault, had they not given Clem the batteries for her walkie talkie at the end of episode 2, she would have never been able to talk to the stranger in the first place.
There is never a single cause to events like these. Except for Ben.
