Who cares if Dawn is a 10 year old cheerleader, it'd be even more odd if Ash is a 10 year old guy cheering for Dawn like in the ending credits of DP062
+. Ash's age hasn't changed a bit in the anime, but it has in the video games. So if Ash and Dawn are both 10, then they're equal at age, not older guy being paired with a much younger girl belief. Even though Ash's confirmed that he was twelve years old after he got his last badge of of the Johto League, in japanese he's still 10. Kind of odd right?
Oh and there's a part in this pearlshipping vid that has ash and dawn staring down at something, then ash like glomps her, and I think it's hilarious XDhahahaha!
