Anyone else notice that the Cheerleader’s Texan accent has disappeared the last few weeks and was replaced with a more typical accent-less “American” accent?

Also, has anyone else noticed that sometimes Hiro understands and speaks English pretty well, and other times he seems not to know any English at all (thus leaving a reason to have his buddy tag along)? There is an inconsistency somewhere in there. (And no, I’m not talking about perfect English, no Japanese accent future Hiro. I’m talking about present day Hiro.)
