I gotta say, awesome that you caught a fully-evolved Azumarill in Petalburg City in OR, although it's disappointing that she has Thick Fat. Cashew 2.0 perhaps?
As for Black 2, awesome to hear Australia evolved into a Dewott. He should be able to hit much harder now that he's going to get some good moves along the way, hopefully he can live all the way because you know, Oshawott line, plus I hope he can replicate the success of Swing from your White Wedlocke. Jamaica should become an Azumarill fairly soon as well.
