So this is Indole-3-Acetic Acid (IAA), who looks a little bit like my botany professor. ^ ^
He is not one of the drug molecules, but a plant hormone.
His greatest ability is to make plants grow roots, and then they'll grow new shoots.
Each of the four pockets on his shirt is full of different kinds of seeds.
If nothing changes my original character description, he's French!
He's also a distant relative of the Tryptamines.
