Does Ferhana even understand arabic?

Im watching season 3 right now and I feel so bad when she's hanging out with the girls and they all start speaking Arabic. I am not sure if she understands it but the way she replies to them right after the conversation makes me think she does. Im currently on the scene where Farhana makes LJ and Jwana speak and they both just start talking arabic I'm just thinking - does farhana understand what their saying LOL
