Actually nobody owes Clem anything. Nobody has to look out for her. Yeah, it's the right thing to do if they do it, but they are not obliged to.
I can see your point Red Panda, and I agree with it. It appears all our training were for nothing because she just does whatever she pleases. She did that the entire season. She's stubborn and yeah I know she's a kid, but as Chuck said, she has to grow up or she'll die. I hope Lee's death sticks with her through her entire life. She needs to know that her stupidity cost him his life and maybe that will be the reason why she won't be the next one to die.
It is really a shame that sometimes only a tragic event can allow us to see the truth that has been in front of our eyes all along. That's life, unfortunately.
If Clem wants to live, I hope she will learn her lesson now.
