Advice isn't given lightly in The Walking Dead.
At the very beginning of season 1 we are given two very important pieces of advice: the first is from Herschel: be careful who you lie to and about what, because you will have to rely on the trust and honesty of your fellow people to survive.
From Kenny in the same scene we got the second most crucial piece of advice: 'taking care' of Clementine isn't just about keeping her safe: Lee will have to act as a parental figure and role model for Clementine: not just a protector.
In season 2, the only advice we have been given so far is 'be careful of wild animals' (then Sam attacks us) and Pete's advice.
Pete's advice was this: Sometimes you have to play a role, even if that means the people you love, hate you for it.
My question to you all: what potential future roles might this allude to for Clementine, or other characters? Perhaps Pete's statement might actually allude to the the future actions of other characters instead of Clementine.
