This is interesting since it will mirror what happened to Lews Therin's reputation after he went insane and Latra Posae Decume took over. But I think the David parallel can still be applied to Rand during his beginings, especially since Rand was a great musician. It was a great reminder how much Rand loved Thom's harp - in this case, one of David's favored instruments was the lyre.

I think the main similarity is that Rand and Egwene are very similar in temperament and thought process; Rand is more akin to Egwene's older brother than a love interest. In fact, he notes in TSR that she generally pretended to be pointing out something as a new fact after he had already suggested it - she adopts his worldview and opinions because she agrees with them and then acts as if she knew before he did...just like a younger sibling.
