Hey there. Would you be up to Hikari and Riku possibly trying to do a pokémon battle at somepoint when they meet up in person again? Since they're both in the same squad on the PGC now, they should probably try to get a better idea of what each of them are able to do in battle.

... Or more accurately, Hikari would probably just want to see how she'd compare to Riku after finding out that she did pretty well against Lightning and having more time to train and her lack of Ground type moves with her team.
