EXCLAMATION POINTS

What is the meaning of the exclamation points over Lisbon's eyes, vs. lines like RJ normally draws? Are they taunts like "checkmate!" Is that a sign that she is left alive vs. the lines that look like dead/closed eyes? Just wondering what clue we could get from that. Maybe they are showing that the eyes are important...Visualize's symbol is the eye and the exclamation points could be pointing those out. No clue.
