Holden's grip on Loki's shoulder stays firm — tightens if anything, as the other man fights him — until Loki seems to see him. The look on his face isn't unsympathetic.

"I know." He doesn't, of course, not exactly what Loki saw. But he knows, the way they're being tempted. He knows, the pull on their memories, their hearts. "But it isn't real. Are you okay?"

He doesn't yet move to let go. Both an excess caution and whatever comfort the touch may bring, in this castle full of specters.
