wrt Mako/Michiru/Nehellenia as a thematic trio, you could potentially spin that Mako and Michiru are afraid of the future cause while their friends have dreams that easily lend themselves to their basic natures (Ami’s already smart, Haruka’s adventurous, etc.) Makoto and Michiru might feel like they’re fighting expectations of what they are/should be, and feel like they can’t break out of those hangups as easily.

KEET YOURE A GENIUS I LOVE THIS
I love that it keeps to the dream theme, and it’s so absolutely true for them. Everyone else has obstacles to their dreams, but for the two of them THEY are the obstacle. Mako has a ton of baggage around the way she presents and wanting softer things from life vs what she feels is expected of someone her size and strength, and Michiru I think more than anything wants to be free, and while that ostensibly means from expectations from parents/society/senshi life, SHE’S what really holds herself back.
