Sooooo, I can't wait till my cousin comes over, so I did this on my mum. Keep in mind, she has a sound knowledge of Percy Jackson by listening to my endless convos about it. Her answers:
Piper: Aphrodite (*She's very pretty, and you said that Aphrodite is the goddess of love...?)
Hazel: Thalia (*I think that this is the famous Thalia Grace you were talking 'bout!*)
Thalia: Thalia (*Oh, so this is Thalia)
Jason: Luke (*He looks mean like Luke)
Leo: Nico (*He looks like what I imagined Nico di Angelo to look like!*)
Nico: Aphrodite???? (she wasn't really paying attention at this point soooo)
Bianca: Liara (*She looks like a Liara*)
Reyna: Aphrodite (*She looks pretty*)
Aphrodite: Athena (*She looks like a goddess*. After hearing the answer. *OH, so SHE'S Aphrodite, I imagined her being prettier*).
Frank: Leo Voldemort...... (*No comment*)
Annabeth: Annabeth (*She's incredibly gorgeous, though)
Grover: Grover (*He's a goat and he has a goatee!*)
Percy: Jason (*Did I say that already?*)
Lester/Apollo: Apollo (*You showed me that picture already*)
Athena: Athena (*Lucky guess!*)
