Tw: mentions of bleeding out, vivisection/lab table, blood, death, and shattered glass.
Ok so I went to this random indoor pool today and for some reason my first thought was "This would be a great place for Danny to bleed out in!" My reasoning is as follows:
The entire pool was made of metal. Like lab-table metal, shiny steel or something. When you jumped on it it clanged and you could feel the vibrations all throughout the pool.
The pool was lit green. So now, we have lab-table metal bathed in green.
The ceiling was glass, and it was night, so as you lie on your back floating, you can see the dark sky.
When you're in the pool, alone, you can hear everything, the quiet swishes as you move your arms and legs, your joints popping, your breathing, and nothing else.
Bright fluorescent indoor lights on the edges of the ceiling (outside of the glass bits)
Together, we have a vast expanse that's incredibly peaceful (lots of time for "I'm almost dead" thoughts), practically tailored to remind Danny of whatever vivisection he just went through, but also perfectly tailored to allow Danny to look at the stars. Plus blood-red will contrast the pool's green, and blood mixes in very cool-looking ways with water. Additionally, shattered glass from the ceiling Danny probably just fell through would also reflect beautifully, perfect shards for Danny to, idk, view his old life in/reminisce/be forced to confront his reflection as he dies. And finally! The obvious stuff one could do with the concept of sinking as one bleeds (I'm thinking bubbles, if that makes any sense).
Anyway, in conclusion, there should be more fics where people find Danny bleeding out in a pool.
