This is definitely nostalgic. While Samus had every reason to be suspicious that something horrible and awful might befoul her on this trip and that there was probably CURSED SPRINGS or SOMETHING WAS CURSED she was so tired of getting worked up about apprehensions and suspicions it and just wanted to enjoy them for what they were. If anything did happen, it would probably just result in a week of aggravation and annoyance. Like clockwork.

Was this what getting older and more jaded felt like? Maybe it was a little nice... felt like heat sinking in her tender back muscles, and soothing water running over her bare skin. Her home hot tub was nice, but this was rather luxurious in comparison.

It would be a lie to say she wasn't completely unobservant; bounty hunter habits died hard after all. The times she was in the women's only spring was for the purpose of added privacy and she certainly wouldn't appreciate that being interrupted (or peeped on, bathing unashamedly nude as she was). Co-ed spring was a different story (a towel was at least definitely present) but Samus was not exactly very social to begin with, keeping to the empty and secluded boundaries of the spring and looking like she didn't want to be bothered.

...especially since she was still wearing her gun in and out of all the springs, strapped tightly to her thigh.
