Of course, when Quinn and the mysterious old healer had disappeared, they hadn't actually vanished, instead they had both appeared inside of the Shadow lock. Quinn didn't want any spectators for what he was going to do next, otherwise he was afraid that it would just make things more complicated.
He still held on to the man's arms, preventing him from taking his own life. After some initial confusion about how and where they had landed, the man concentrated on trying to free himself by attempting to kick Quinn off. However, the latter noticed his hostage's intention and made the first move by hitting the other's shin, breaking the bone immediately. The force was strong enough that his leg had banged into the other dealing some excruciating pain.
"It would be for the best if you didn't move." Quinn instructed the man, whose eyes started to glow red. There was no point pretending to be a healer when it was just the two of them, so he was revealing his true colours.
