A male voice: "Morikawa left fifteen minutes ago."
(Kaede recognizes the speaker as Yorihisa Murimora.)
"I don't know. Probably to perform the rescue operation."
"From the school."
"Waiting for Hirokazu to figure out where to send her."
"Not really. I wasn't paying much attention to them."
"Morikawa got fed up with Hirokazu.  When he finally found what she 
  was looking for, she stormed off, telling Serizawa not to let him
  do anything stupid."
"I don't, really."
"From what I can gather, Hirokazu traced an IP to find a street
  address."
"I don't know. I'll see if he's left it in the history files."
  There's some waiting, then: "That figures."
He gives an address.
"Yes, I know Hirokazu. That's why he'd think to check there.  Go to 
  the site and see for yourself."
