Honestly, the 90s anime, especially the first season is infested with filler episodes. With those on the table, the characters remain in their default character for so long we forget whatever development they get and treat those f th as out of character bits.
An example is that everyone remembers Usagi being a crybaby who doesn't want to fight...while in the first season her crybaby I-dont-wanna-fight freakouts last for barely the first 10 episodes. By the time Mars comes around, Usagi does panic a bit over battle, but she learns to get over it on her own.
By the end of the season, she has learned how to defeat enemies on her own and when Luna restores her memories in R she immediately gets back all her confidence.
So,funny comic, but irrelevant in the whole picture.
