Arwen's Mortality

[Alchisiel]

As in, if her father wasnt Elrond and she was a regular elf, would she be immortal still if she stayed?

I think everyone has missed part of the question here or I am reading it differently than everyone else, so I will put my two cents in. If Arwen was an elf and not half-elven and stayed in Middle Earth and married Aragorn she would eventually "fade." I believe that in LotR it says that if the elves didn't go to the west they would eventually "fade" and/or become a rustic folk. I can't quite remember where I read it.

I don't think that elves and dwarves would ever get together like that. I think the elves thought the dwarves were too...hm,.....uncouth I guess you would say. As for the hobbits I believe that it is said that Frodo had an elvish look about him and that one of his ancestors might have been a fairy or elf. Logistically I don't think a hobbit and an elf could get together, if you get my meaning as Sam would say. After all hobbits are pretty short.
