Have him collect beads with you

"Right. Sure." You look around at the exhibit floor and pick up a discarded plastic bag. "Just one thing. Can you help me pick these up before anyone else gets affected by one?"

You ascertain that he frowns by the movement of his eyebrows above the dark shades and takes it. He watches you start to pick up the beads in your own bag and copies you.

"As you can imagine, the government is concerned about all outbreaks of, let's call them, artefacts of abnormal nature."

You look up at him in surprise.

"This is not the first time something like this has happened, believe me."

You look even more surprised.

"Well, never at an exhibition of historical sexual artefacts. This one is going to be particularly difficult to stop the press covering."

You get back to gathering the glassy beads, observing their various vibrant colors as you pick them up.

"Your colleague, Camilla, made contact with me recently. She talked about a concerning discovery. Do you know where she is?"

You look up from the beads you're collecting, "I wish I knew where she was, her knowledge of all of these things would be pretty useful right now! I didn't believe her about most of it until today."

"Well, it's imperative that we find her quickly, as well as whoever did all this." He gestures at the museum hall. "Can we examine your camera sys--?"

A loud moaning noise from behind distracts him. You both turn to see Nadine once again wobbling and convulsing against one of the smashed exhibits.

"Poor girl," you say. "I'm glad that didn't happen to me. Come, I'll take you to the security room."
