I thought there'd been a story behind this one but I forgot it. (That's how long it took me to finish the picture....I'm easily distracted.) It's probably something like for Arthur it's either at least 4 hours of actual sleep or none at all. A couple of hours make it harder to shake off the grogginess after waking up. The hairpins are probably Philipa's or Ariadne's or Eames bought them.
This one is a Stuart: a life backwards and Hesher crossover. Haven't seen the latter and don't know what the movie is actually about. I just felt like drawing these two together.
