Does anyone know who is Ryder's secret online friend?

I need help guys and im so obsessed of this girl identity... At first i thought it was Tina because she is the only one when the glee/グリー Members are inside in the choir room and she's outside but we all know that she's inlove with Blaine so i got her out of the picture... I don't know maybe it's Jake because he wants to know if Ryder is totally over Marley... But i really hope it's Marley...
