[Hold on, let Sugawara wash down that forkful of pasta with a few gulps of water. ]

There've been rumors that one of Oikawa's men has been seen loitering around [where they were earlier]. They say you'll know him from his distinctive hairstyle. I want you and Hinata to check it out.

[He'd send just Kageyama,but if Kageyama can recognize this invader, then that person must be able to recognize him too. At least Hinata can get close enough without triggering as much suspicion, and Kageyama can keep guard from a safe distance... and try to keep Hinata in line.]
