Now that I actually have the time to look into these things again...

Nurse is the one who helped Emi after the loss of her legs, re-learning to walk and all. He's either a close friend or honorary family after that, hence the close relationship with the family.
That particular scene is 'An Apple A Day', to which the Nurse said that he and--presumably the Ibarazakis--have a more "familiar relationship than is strictly professional"
Hisao then followed by saying that the nurse seemed to be embarrassed and that he'll keep it discreet.
This part of the chapter explains the relationship of the Nurse and the Ibarazakis to a certain degree that:
-Nurse has known Emi far longer than Hisao
-Nurse was involved in Emi's amputation
-Emi and Nurse shares a familiar but close relationship.
Next, on the chapter "track meet".
Here we are introduced with Emi's mom. As we know, Emi's mom watched the first couple of races before a text message from someone--to which she said "text message. What is he, sixteen?"--forces her to leave and meet up with this individual.
Guess where's the Nurse during that time?
On the next chapter, "Down that Medicine Now", the Nurse was checking on Hisao's condition to which the conversation turn in favor of Emi. One particular line the Nurse said that caught my attention is this:
"That she was, Hisao.
I watched her first couple of races before I had some business to take care of, but she told me all about it."
So the Nurse
was at the track meet, but left at about the same time Meiko did. Coincidence?
on the same chapter, the Nurse actually reveals more about Emi and her relationship with him. Their familiarity is enough for the Nurse to read into Emi without having her tell him everything--not to mention, they gave the same line to Hisao:
"Take your damn medicine", followed with the Nurse smiling 'as if he's in some joke [Hisao] doesn't know of'.
I'm starting to get a father-daughter like relationship between Nurse and Emi--or as close to it since her biological father is off-the-grid. That, or the Nurse happen to fill the 'father figure'-role for Emi after her loss, so I'm seeing some possibility that the Nurse
might have something with Emi's mom and is waiting for Emi to get over her past and accept him into the family--though, this last bit is still more or less a theory.
...huh, interesting. I might actually bump Emi up my favorite...
