Yes!!! Rhaenyra's words are perfectly in character for her. Alicent sacrificed her relationship with Rhaenyra for the safety of her family and Rhaenyra is bitter.
BUT WHY IS ALICENT NOT DEFENDING HERSELF ðŸ˜. She should be furious. Remember Driftmark, where Alicent rushed at Rhaenyra with a knife?? Remember "where is duty? where is sacrifice?" Because the showrunners clearly don't.
this was actually very in character for rhaenyra to still believe that she’s the only one between her and alicent that has ever suffered and gave things up like at the end of the day she’s still the teenage girl who thought her best friend seduced her father
