SJM saying that Rhys is allowed to make mistakes is hilarious to me because nothing he's done in the series regarding Feyre can be categorised as a mistake.
Drugging and SAing her UTM, making her go into the weavers cottage to get a wedding ring, not telling Feyre that they're mates, not telling Feyre that he's going to sacrifice himself, hiding vital information about Feyre's body and pregnancy from her.
All of these are things he has done knowingly while being aware of the risks and damage it causes.
He knew she would be under the influence and still let her get humiliated.
He knew the Weavers cottage could be a life-threatening situation and STILL went through with it.
He knew Feyre wouldn't react well to being his mate and would not react well to him sacrificing himself and STILL kept that from her.
He KNEW Feyre didn't like secrets and decided to keep vital information from her regarding HER body from her and made EVERYONE lie by ommission to keep her in the dark.
None of these by definition are mistakes. And they never have been. He knows what the outcomes will be and still decides to do them.
How many more "mistakes" is he allowed to make in the name of "protecting" those he supposedly loves before he's finally held accountable for the damage he's caused?
