Viggo narrows his eyes curiously. That's definitely not anywhere near what's happening to him. He takes another drink of the whiskey.

At the question he pauses for just a brief second, then shakes his head. Christina isn't a ghost. She's just his mind playing tricks on him. He glances around himself, half expecting her to turn up, but no, nothing there.

He's half tempted to share, given it's probably unlikely Klaus will doubt him or call him out, given everything he's been saying. But the only person Viggo has ever mentioned it to was a man he seconds later shot to death. So.

Instead he looks over at Klaus. "No offense, but you're aware how crazy you sound, right?" he asks casually, no actual real judgement in his voice.
