while i fill up the queue, a bonus poll:
What's with the shipname smartwater? Where is that from?
"Smartwater" is an old proposed alternative ship name for Percabeth, in the ship name style of using alternative phrases or combos of words rather than just combining character names - in this case, "Smart" for Annabeth and "Water" for Percy each signifying their notable "powers", and jokingly such as the brand Smartwater. In it's original form it wasn't particularly meant to be taken seriously or expected to be used.
It's come back into circulation recently as a means to specify show!Percabeth versus other iterations of Percabeth, not particularly for any reason, but the distinction does help for those being introduced to the franchise through the show only and who are wanting to avoid spoilers.
