Talk:Rey's brain

Purchase-Price Clarification
Does anyone have more details regarding the following, "It can be bought from Old Lady Gibson at Gibson Scrap Yard for 700 caps, less with a skill check (free with a speech check regarding immortality), during the quest, Nothin' But a Hound Dog."

How much less and for what skill check (barter at what level, speech at what level, science at what level, etc.)?

Regarding the "speech check regarding immortality" -- it would be helpful to clarify this on the page. I had to check the page against the O.G.G. (the so-called Official Game Guide book). Page 227 of the O.G.G. says that the price will be reduced to 571 caps with a Barter of 70 or higher (thereby convincing her that Rey will receive immortality by joining his brain with Rex's). This indicates that it is a Barter-level check, not a Speech-level check.

In addition, according to the O.G.G. (at least, by ommission from its flow-chart), Rey's brain is never free. Is the O.G.G. inaccurate or incomplete (it wouldn't be the first time)? It would be super if someone can include the details on how Rey's brain can be obtained for "free with a speech check regarding immortaility."
