It's worth pointing out that Elladan and Elrohir had not yet been invented at this time.

BTW, I read that section of HoME backwards and forwards, a few months ago, and I came to a very different conclusion than CT about when JRRT took his long break. Granted, CT had more material to consider than he's given us, but from what we have, the texts can be attributed differently than he suggested, in a way that can be enlightening.
But that's a discussion for a different thread, and I don't have time now to pull my thoughts together about it. Maybe next week.
