[discussion] In defense of Ram
Ram saying "I feel bad for Rem" and many fans took it at face value.
First of all if we go back a few episodes ago, she literally was about to sacrifice herself for Subaru. So with that I think we can tell that she does not hate him.
Now onto the main point. Ram always speaks with thorns and we can tell that theres more meaning in her words then whats at face value, there is almost always a double meaning for her thorny words. She avoids showing that she cares using thorny words (I hope we learn why she does this).
So with that we can take "I feel bad for Rem" from insulting Subaru (Face value context) to her expressing her feeling bad that Rem is now gone, no one has memory's of her and one of the people Rem loves the most has forgotten her.
