I hear mention of Rocket Radio, but I've only ever got what it's about from here. Sounds pretty interesting. If only there was a way for it to be translated... perhaps.
Who will say it first???
I can see James goofing up and it slips out, but otherwise, they're rather stubborn about mentioning such feelings. Meowth is the one with the big mouth, and he brings it up a few times in the series (biggest one comes from the second movie). If what he says is true, it's possible Jessie and James are aware of their feelings for each other, we just don't see it onscreen.
