Immortality and the sons of Elrond

The life of the Eldar until the choice is made, that's how I would put it -- at least with respect to fate, which is the main concern.

'But there will be no choice before Arwen, my beloved, unless you, Aragorn, Arathorn's son, come between us and bring one of us, you or me, to a bitter parting beyond the end of the world.'

As I read it this can easily mean that Arwen will have no reason to choose mortality -- in other words, Elrond knows his daughter, and thus knows she will likely pass Over Sea with him if Aragorn were not in the picture. Aragorn has just said (directly before this) that the choice must soon be laid on your children, and Elrond responded 'Truly'... and then goes on to say the part you quoted. This fits with the earlier statement in Appendix A.

Arwen is not default immortal nor default mortal by virtue of the choice -- and Luthien is an exception. Arwen's choice merely echoes that of Luthien's, and she would have arguably chosen an Elven fate had not Aragorn been in the picture (again, which is what I glean from the quote you posted).

Theoretically 'a mortal' of course, but as the history turned out, specifically Aragorn and Beren.
