In spite of himself, he gets entranced by the mysticism of the display, one hand reaching up like he might actually attempt touching one. What Merlin doesn't know is that this is something normal here; the abilities aren't anything he'll have to hide, not where magic is sometimes even used during daily mundane tasks.

Sizhui's fingertips almost brush a sparkling butterfly as they start to disappear and once it fully vanishes, he withdraws, rubs the pad of his thumb over his other fingers then grins so exuberantly, it's a wonder he can contain his excitement.

From a nearby shelf, he removes a piece of red paper and folds it carefully, meticulously into a pretty haitang flower. After it's finished and set in his palm, Sizhui reaches the opposite hand to hold his first two fingers straight up, eyes shut in concentration, then they reopen as he drifts both digits over the paper. It alights with a brilliant spark, petals suddenly translucent-looking like a miniature lantern that he offers Merlin. See? Everything's fine, nothing to panic about.
