amira-ragab sent: Hi sorry it's me again my question is when someone is sick you will send him to the nearest hospital maybe that's what happened with Rize. Souta attacked here in that place to make sure she will be sent to kanou and he chose her because she eats too much the possibility of here eating there would be higher than a normal ghoul AND the RC Cells don't affect the five senses kaneki now wears a glasses and Urie said something like that after the operation thank you

tokyoghoultheories:

I guess that it would be possible that he wanted Rize to become Kanou’s “Kakuhou donor”, but we still need a confirmation for Souta’s motives. 

As for the RC cells, it does work on all the senses, but only in ghouls. For the Quinx (who theoretically are 20% ghouls), it seems like all of them have particular good senses, but only one per person: Mutsuki - vision, Saiko and Shirazu - hearing and Urie - smell. After his operation, I assume Urie expected immediate increase of his senses, specially smell, but it did not happen:

I assume their senses became that sharp gradually. With Kaneki was the same.

In the beginning, his senses were pretty much the same as a human’s (he wasn’t even able to tell if Kimi was human or ghoul):

However, his senses became sharper with time:

We have seen that, although a ghoul can heal (Kaneki’s regeneration skills are really high too), sometimes the damage is too much and there can be consequences. For instance, after who-knows-how-many-times Kaneki’s fingers were cut, his nails became black; this is called subungual hematoma (basically, there’s blood under his nails):

So, based on this, it’s safe to say that, after having a centipede in his head for a few days…

…and after having his head stabbed twice through the eyes…

…there were ought to be consequences:

• The brain damage caused him amnesia and coordination issues:
  

• The damage to his ear limited his hearing to that of a normal human’s:
  

(He couldn’t hear Nutcracker).

• And the damage to his eyes created the necessity of using glasses:

Still, his smell (which happens to be the sense we got more hints of) is still pretty good:
