I am glad you agree with us that there is potential for Ressler and Liz.
I agree with you that it is hard to say which couple is going to be endgame. If any couple is going to be endgame for that matter.
Liz needs to find out who she really is first in order to let somebody in her life that truely cares about her. For her and who she is and not because it was a job. I know that Ressler can be that guy for her.
