Thank you! :D
I had to do a bit of research... I didn't want to rely only on the show for obvious tomatoes reasons.
Actually, I think the most difficult to draw was the vial: if Arthur SOMEONE had to hide it, say, behind the pillow, the vial could tip to the side and open and the oil would spill out. How can you get a stopper to stick? So I did all these sketches with various knots and strings to find a fastener that was easy to use. Shame that all the details got lost in pix-hell.

(scented oils FTW!)
