6/27/20: I really like the way Rob's jeans turned out in the 3rd panel.
6/30/16: Rob's assigned to watch Lethe and help her out whenever he can. Lethe has the compass on her right now, and her movement can be tracked fairly well, but Rob doesn't have a cell phone or any instant methods on which he can be kept up to date on Lethe's location. Less instant methods exist, like sending a messenger, spell, or whatnot. I don't think Rob even knows that she's being tracked. I wouldn't be surprised if Fianne gets busy/distracted sometimes instead of keeping tabs on Lethe all day.
Well, it's basically an excuse for Lethe to be able to roam around a little on her own.
