Help Desk - Property/Replacement Issue

[warrantofice]

Alright,

Brother collects some comic books

I borrow comic books

GF spills beer on one comic book

I tell brother that GF will buy new comic book

Brother asks if GF will buy the 'next' comic book (next on in series)

GF refuses to purchase the next one, will only replace damaged one

Notes: It was my beer, but that shouldn't matter. The comic book was no an original. Brother did have the complete series.

Q - (note: i am having trouble wording it correctly)

Assuming that my GF claims the responsibility to replace the comic book that she damaged, is she only required to replace the initial comic book. And is my brother wrong or have no right to ask her to instead purchase the next comic book. Are they just completely seperate enties that have no connection and does my brother asking to buy a different one, mean that he does not care about the one she wrecked and therefore she does not have to replace it.

Also note that my brother did keep the comics in great condition.

Obv not that important i'd just be interested to hear what people think of this. Thanks for any responses.
