I'm definitely in agreement with you. Pokemon games are very mysterious in certain scenes and aspects - it's why I adore theories so much. You never know what a fan will come up with that could make way more sense than you'd ever imagine. Leaving it up to our imaginations makes me even more curious and is a wonderful recipe for plenty of good fanfiction. :)
But welcome to PC, Ari! I lovelove your avatar as I'm a huge Larvitar fan, it's always hard to evolve mine since Pupitar and Tyranitar, although cool, will never match up to its cuteness. Though I plan to train one in my X version when I'm done breeding other Pokemon. Glad you're enjoying Silver! Be sure to check out the Metal/Color Generation Gaming board to discuss the first and second gens if you're mostly into them.
Keep on posting around and be sure to let the staff with blue, orange, and red names know if you need anything! We're all very friendly. Stick around as well, all right?
