Iâm realizing that it is highly likely that Ryland Grace was padded during his mission on the Hail Mary, as well as afterwards, on Erid.
The book and movie both begin with him waking up from a for year induced coma, with the book detailing him incorrectly removing his urinary catheter. This appears urethral and sphincter trauma, evidenced by the pain and blood that trails onto the floor. Incorrect removal of a catheter in this way would most certainly cause at least temporary incontinence. In addition to this, relying on a catheter for so long would lead to bladder atrophy.
In the book, on his first day of being awake, he expresses concern that quite some time had passed and he had not yet felt the need to urinate, realizing he should likely try before he inevitably urinates on the floor. This suggests that at least in this point of l the story he is unable to feel the need to use the bathroom.
In addition to the damage his body had already taken, being in space greatly affects the bladder. A zero or low gravity environment most often makes it difficult or impossible for astronauts to tell if they need to urinate, this means that astronauts are required to wear diapers in certain situations. This means that the Hail Mary would be stocked with adult diapers just as it would any other necessity.
The damage from the catheter may or may not have been permanent, as we donât know how severe his injuries were. If he wasnât though, the trip back to Erid likely weakened his bladder causing the need for protection, even within the artificial gravity, once more.
During this trip, he begins to suffer from malnutrition, leading to scurvy. In the book, he begins to suffer many degenerative health effects as a result, including tooth loss and reopening of scar tissue, incontinence as another side effect would be a likely conclusion.
Once in Erid his body would likely still carry some long term damage, even after getting healthier he would still likely have lasting damage. The book details that Erid has a Gravitational pull of 1.5 that if earthâs, living in this high pressure environment for an extended period of time would further damage his muscles, causing atrophy and mobility issues. The book shows his now using a cane to walk, the visible detail of his weakened body.
In conclusion, I believe that the evidence points to a near certain likelihood that Ryland Grace is padded for a majority of his mission in space, as well as his time later on Erid. I hope that this composition of real-life facts and Canon book evidence can help anyone wanting to make their own headcanons or FanFiction including Padding in Project Hail Mary.
Bonus: I do headcanon that by the time he was running low on food, his supply of padding would be dwindling as well, leading him to change less frequently to conserve the necessary resource for as long as possible. This begins to lead to rashes, ones that his weak body struggles to heal. Rocky sees this and is concerned so he engineers reusable, comfortable, xionite padding. I headcanon that it ends up being more comfortable and absorbent compared to the standard disposable diapers that the ship would have provided.
*nodding nodding* VERY in depth, flower!! It all definitely makes sense! And definitely a very good reference point for anyone who wants to write/draw padded stuff for Grace! Very nice, genuinely thank you!!!đ
Grace 100% caused some semi/fully permanent damage after he pulled the catheter out while still fully inflated (I still physically recoil at thatđ) which definitely has him requiring some padding or a form of protection!
That was thankfully thought through and so there were plenty of diapers packed (certainly not for what Grace did to himself but, regardless) and thankfully Grace finds comfort/is soothed by this security thing ;w;
(And oh my goodness noooo poor Grace ;^; no buddy we can't be having you get rashes ontop of everything else! Rocky definitely develops a cloth-like padding for Grace because he hates knowing Grace is making himself suffer more đđ)
