Yeah, the Aragorn/Arwen thing is basically just in an appendix. Sort of "if you're interested, here's what happened in the past." But it doesn't go against anything with Aragorn from before--nor does Rosie with Sam.

I'm trying to remember exactly what my reaction to 3x1 was. Maybe I was just expecting Mai/Zuko since seeing that she liked him as a kid? Because that was pretty much enough for me. That he wasn't crushing on her the same way back then was explained by him being 16 now. I don't remember if I was surprised by his casual PDA. I tihnk I just thought he's 16 now and he has a girlfriend. They've been together for long enough that they're really into making out and leaning against each other. Thinking back I guess I felt like I knew how they got together. If the show didn't give me a special story for it I figured it was just so ordinary it was boring. Mai thought he was hot, he thought she was hot. They probably talked together a lot, making slightly stilted conversation. They went off without the others and thought the other one was cool and then that led into them going out. Since neither of them had been with anybody else when last I saw them it didn't seem jarring to me. I didn't need a particular sign that he was focused on her before that because I figured he wasn't.
