okay with the faq question answered, would strengthening his water powers so he could control water based liquids like paint be acceptable? (this is the direction i was heading in with water control in the first place.) he'd control them similar to water (though of course couldn't just conjure them up like mers do water), and he wouldn't be able to control blood inside of a person (though maybe outside of one would be possible? not sure since this is just tier one.)
