I would say kid Grace is adorables, but that's a bit redundant. Grace just is adorables.
This wasn't my intent at the time, but the design of this mysterious scientist reminds me of Gordan Freeman of the Half Life series. Of course, that's not difficult to do. All you need is a scientist with facial hair and a goatee to do that. Still, I did so unintentionally, as I wouldn't be personally familiar with that character until years later when playing The Orange Box.
