I'm not sure about being worried about Kiko, she did go out the nite before and I would think shes suffering from a massive hangover all day, and was not feeling well. Earlier in the day it seemed that she was perhaps still a little tipsy, being loud and obnoxious with Jenny, but when Jenny went to her room and Nora stayed on the floor and tried to nap, I would say it finally hit her.
At least that's the way I saw it, but that's only my opinion.
