well i must say, focusing on Dawn's team at the moment, i am pretty dissapointed. The rushed her capturing, and she seems to be more of a comic relief than a coordinator, and, frankly, everytime i think of her and her "pokemon" i get a headache. Now i don't want to cause flaming for those Dawn lovers out there, but i find it hard to believe that they will have her catch a pokemon in a movie. That never happened before, and i am not too sure, even if in coro coro magazine, that this is true. But if it is, i am prepared to resign myself to what could possibly ruin the 4th generation for me.
and as for your post above, Lucario At Service, i must say that your prediction is right on cue, if Dawn does catch Buizel. Although the one part of your post i dissagree with is the section where you describe her situation as "Interesting" i would call it "painful" and "chaotic" to say the least.
I know my opinions on Dawn are strong, and not having seen the episodes personally, maybe a little rash, but at the moment, that's what it is.
However if she does catch it, this does leave opportunities open for Ash, and i would love for him to have a shellos and a lucario (considering Bronzong is out of the question as he has never had a psychic type, and would be too dense to use it in the first place.)
