What questions does mark twain raise about romanticism/realism in huck finn?

Tom sawyer represents his ideas of romanticism ( like in the end when he comes up with an overly ornate plan to free Jim), Huck is essentially realism in that he has no epiphany to change his ways and is neither completely good nor evil (seen in his conversation with Jim about stealing from farms while on the raft). Twain is trying to point out that romanticism is pointless and in no way represents "Truth" and that only in representing reality as it is seen and without the ideals of the writer can history be preserved.
