I pondered about an issue and concluded I may be a baggageless man, or the next best thing (language issue, not other allusions). Indeed, I learned my English via Tolkien, and all I've read seemed natural to me at a time. To an extent that my own vocabulary consisted of 'lo!'s and 'deem's at earlier stages, and I've been accused of talking 'archaic garbage' once on another forum. Yet, having little notion of how 'modern English' should sound, I found it normal
On the other hand, the change of style does not break anything for me even now, when I have acquired some bags, for it also seems natural - further hobbits (the nearest thing to modern world to be found in ME) get from the Shire, more olden everything gets. It feels like diving into time, and the deepest levels should contain ancient fish, not found on the surface. I would have been dissapointed if Eomer recited in Bilbo's 'bussinesslike manner' reserved for people trying to borrow from him.
That would certainly break the enchantement
Besides, events acquire almost biblical scope towards the end - it is the
Black Gate to be passed by the
King symbolism, it seems suitable to speak 'high'. (I know I mostly repeat Lalwendė's post here, I just want to add 'Biblical' to the 'to reflect the importance of the events taking place')
It uplifts rather than breaks. But individual cases may vary, of course.
