Also, also, your version is now slightly ambiguous since it is not clear whether Froderick is speaking Twin Earth-English or English. If he is speaking English and just happens to be on Twin Earth (ie. if he is Frederick's identical Earth twin and has been transported there unbeknown to him) then the context is not enough (or may not be enough - there is, I believe, some debate about this point) to change the meaning of his words and so his words may mean the same as Frederick's. That is why the point was made explicitly in my last version.
