OH GRACIOUS I thought I'd replied to you already. Sorry about that, I've been busy and away from the internet and all. That aside, I'm glad to have you reading. That certainly sounds like an interesting suggestion - it could work. Thalia doesn't have a Pokemon of her own, so it's definitely something that bears consideration.
Just noticed your fan fic and began reading it just moments ago, and got to Chapter 2. I wanted to say that I love the concept and wish this were actually made into a real story. Something I'd kinda like to suggest(If it wasn't done/suggested already), is that Ren finds a Pokemon to send home to keep his mother company. But, now I'm moving onto Chapter 2 in just a bit. Hopefully will be caught up by next week. :3
