Flora, Tecna, and Stella's actresses... DOUBLE UPDATE!
Thanks to Ella and Anonymous for getting the names of Flora and Tecna's voice actresses!
Oh, and *update* from the comments, Stella is Amy Gross!
Steph (the girl from the Facebook post) asked Molly Quinn, and Molly revealed that Flora's voice actress is Alejandra Reynoso! I had asked Molly about Stella and Tecna, but I'm not getting anything helpful.
Anonymous talked to Romi Dames (presumably over Twitter or Facebook) and got the name Morgan Decker for Tecna. Sooo I tweeted her (or whatever you Twitter people call it ^.^) and she said YES! ;)
