I keep hoping each new episode will give me a reason to root for Nathan since I know she wants to pick him in the end but it's so dang hard! She got mad Lucas for sending her chapters to his mom (yes wrong for him to do without asking and definitely awkward since it's his mother) but no matter how Nathan acts she just brushes it aside and still wants to go out with him. I just don't understand his appeal personality-wise (no offense to Kevin McGarry, who is great and is just acting with the material the writers give him). If she wants to go out with him, then fine, it's only fair to give them both a chance but he can't even ask her and it's so frustrating because he does come across as a teenager instead of a grown man like you said!
Has anyone watched the sneak peek clip for the finale? It basically shows Nathan about to ask Elizabeth out, getting distracted, her giving him another chance to ask, and then him saying, "nevermind, maybe another time." It doesn't seem like he'll get around to asking her at all, then he'll probably be the one to get shot, the season will end on a cliffhanger, and then love triangle will STILL not be resolved.
