"Hope," he answers instinctively, as he hears her call out to him, even a room away behind the glass. His energy isn't returning to him. Whatever is in Hope's IV must be in his. Perhaps, he was given a stronger dose. He keeps to what he knows. Hope is in that chair, and whomever is with her is taking a sadistic pleasure in performing the procedure while she's a) awake and b) in front of her father. Everything is unacceptable and Klaus can all ready picture himself ripping into his throat.

Klaus doesn't feel anything at first, no sensation of pressure. But, from the conversation he had with Clarke he half expects what's going to happen. Johann said as much. A reaction between the two of them.

With how bloody Hope had been in the hotel, it's only natural she'd been injured too. Injuries heal, but they also sustain. Could his power be tied to his daughter's pain? If so, then their powers are more than metaphorical, they're literal torture.

"Hope, stay calm," he says underneath his breath, knowing only she can hear him. "We will get out of here and we will drag this man's entrails behind us as we escape our shackles. It's going to hurt, but you're a Mikaelson. Don't give him any more pleasure than he's all ready getting from this sick voyeuristic show." His words are slow, but deliberate, as his eyes search around him, search for corner camera where Cassius must be watching from. He tries his arm again, tries with all his might to move one limb.
