Jean Francois has always looked like he’s looking away to the side. Aloof and confident, pondering about life and battle. It’s a really cool artwork of him. But in reality…
If you don’t look closely, JF looks like he’s staring to the side. There’s a red glint on jf’s eyes, when it fades away, you actually see that he’s staring at you instead
If you’re using an iPhone, click the image and the second one will have his head slightly lower and as you say, his eyes are different in the second one
Red glint in Jean Françoise only available if you look at the full body animated portrait.
Aside from the small description Musketeer Mage that is his epithet. I have always thought there was little more to him.
My theory is that JF is not human, but rather he is a Dhampir - A half-vampire and half-human hybrid, having the strengths of the vampires, but none of their weaknesses. His innate ability is that he is immune to drain-life type ailments, which are, not surprisingly, used by the vampire heroes (Victor, Valeria, etc.)
Red glint in his eye might be a reflection of the vampire side of him surfacing briefly.
He may also be a hunter of vampires, he is a practitioner of fire magic, while may not outright kill vampires, but could slow them down enough so his rapier, which could be made of silver delivers the final kill.
