Pfft. You don't need to rewatch s5. You could just use whatever parts you remember and want to use and then make up the rest. It'd probably be better that way anyway. ;)

pesky eyesight troubles? That sounds less than ideal :(

And no worries, re: fic. It's pretty much just self-indulgent threesome porn anyway (or well, that's what I intended it to be, but the characters wouldn't shut up, so I mostly totally failed at that in the end)
