Ed slumps in Cipher Nine's grasp and lets out a long sigh of relief. "Thank you," he says, sounding rather exhausted.

Cipher Nine sets him gently against the nearest wall before heading over to the boy, taking a close look at his wounds and retrieving some of his medical equipment from his belt. "This might tingle," he warns the boy, relying on Harry for a translation into Swahili. "A lot, actually." Then he sets about his work, carefully sterilizing the gash, then dosing it with kolto. The translucent, pale green liquid will, indeed, cause an intense tingling, but it starts to go to work after only a few moments, slowly knitting the wound back together.
