Mona Lisa

You jump in the portal leaving Joan of Arc behind. You probably caused all sorts of time mistakes. But hey, as long as you got some, right?

You fall through the portal and land in a room with several paintings.

You walk behind a curtain and see someone. No ... it can't be!

"Are you the one who will paint my portrait? ... The great artist?" the woman says.

"Holy crap! It's Mona Lisa!" you think.

"You look different than your portraits," she says with that winning smile of hers.

"Creative license, I'm afraid. Now, may we paint a different portrait than we planned?"

"You are the artist. I'm at your command"

"Now when I, umm, paint it ... it may look very ABSTRACT," you say, knowing you have no painting skills.

"Very well," Mona says.
