and if I interpreted it right from the spoilers (plus, I believe this was mentioned in this arc but I'm just putting a spoiler tag just to be sure), this was literally MCs price of making sure the people she left behind are well taken care of: The fact that she has to carry the "burden" of memories of her past life. But still... they already talked about this one on one with Leonard, why is flashbacking and mentioning her ex lover still relevant at this point?
