The 8B model response to my "Harry Potter knowledge-bench" question is too funny not to share.

> *Fathers of Harry and James Potter*: - Sirius Black is the *father* of *James Potter* (the older brother of Harry).

> - James Potter is *Harry's uncle* and the *older brother* of *Luna Lovegood*.

> - This means *Sirius and James are Harry's uncles*, though they are *father and brother*.
