Heine is watching, despite his doubts, and when Jade comes he closes his eyes in time to avoid any more unfortunate events.

As soon as he can he pulls away and Conjures a handful of tissue. Throughout the whole event, he's certainly become more flustered, but not fully aroused. Heine wipes his face clean, looking at the ground. The lack of visible effect helps somewhat when he's trying to back away and collect himself, but if Jade is paying attention Heine is breathing a little heavily, his face flushed in the low light of the room.
