Chapter 2, page 7, panel 2. "This is a Subleseed Crystal..."
Chapter 2, page 14, panel 5. "I knew that Subtleseed Crystals..."
Either there's a "t" missing from "Subtleseed" in C2P7/2 or an extra "t" in C2P14/5. Strips #029 and #037 (in the online archives) both spell it as "Subtleseed crystal", so I suspect C2P14/5 is the correct one.
If I'm nitpicking then "Crystal" (in both cases) probably shouldn't have an initial capital -- "Subtleseed" being the proper noun (i.e. the name of a particular 'thing'), "crystal" being a common noun (i.e. a type of thing).
