That is not Clem. You showed Clem how to survive on her own and when you died she needs to go her own way not find another random man. Those two people on the hill better be walkers. Omid and Christa are most likely dead. Dont you think Clem has seen enough to run away and you can tell Clem to not trust.
Lastly After all you have done as lee to make clem who you want why would you put in a new character to develop.
