Berat's not as patient as you would think...I happen to know that underneath, he gets VERY ticked-off with Speros. Speros despises Berat because of his physical disability (also for his youth, but mainly because he's disabled), and Berat knows it. It's very hard for Berat--regardless of this being an older man and a more senior gul--not to just yell at Speros and insult him right back.
As for Rhos and her possible fates...it's VERY difficult to say what's going to happen to her at this point. I'm not even sure myself.
Thanks for reading!
