>>117153572If I had to guess, I'd say that Marcy went along with alot of the stuff Sasha wanted to do, but unlike Anne who was coerced, Marcy did it because she genuinely had fun with anything that could get them into trouble. While Sasha knew Anne might not want to do something, but had her do anyway, I assume that Marcy simply wouldn't consider how other people would feel about something because she was so caught up in her own head and what she was doing.
For example, the idea that Marcy does not want to go back home. She's clearly having the time of her life, and could possibly sabotage their way home because she's thinking "Man it's so great being an isekai protagonist! I live in a castle, have all these really fun and dangerous adventures all the time! It's just the best, why would I want to leave? Why would *anyone* want to leave?"
Unless Anne screams at her "I want to go home now because of everything I miss back there", I think Marcy won't get just how much she actually wants to go home.
