Aw, thank you!
Until you pointed it out, I hadn't realised how heavy this chapter was on references back, and I'm certainly glad you see that as a positive. I don't know about well-researched - I'm bluffing through a lot of this, though I will admit to being dorky enough to looking how Social Security numbers worked and making sure Henry got an Illinois area code, though I don't know if it's the right one for Bloomington - but if it works for you, that's the main thing.
