(Regarding the scene when they are talking about Helion)
I know Rhys was probably just riling her up. Because how would territorial Rhys be ok with sharing his mate? This reminds me of the nessian cut scene (which sjm admitted was basically fanfiction smut lol). But nessian weren't together so I guess better. But this concept would ruin feysand me thinks. Not to mention very out of character for both of them. Given how devoted and territorial they are.
