ok first off I Amore how the 2 people in the seminare, scrofa with funny names are the cute couple and my domanda is do te think Byron already knows??

No I don't think he already knew because there are points when Byron thinks Ezra likes Ella. I also don't think it is possible because its not something that would have ever crossed his mind especially because he thought Aria was mature and responsible (not that she isn't). So no I don't think he knew if anyone Ella may have had some idea
