Ooh, that Athena/Aphrodite headcanon is extremely RTMI. Especially if it's the sort of situation where Aphrodite starts out just trying to prove a point/her superiority/whatever, and Athena's determined to not be interested--well, maybe she should investigate for science--maybe just a little bit more investigation--and then they both end up kind of in over their heads and way more emotionally entangled than either intended.
