Schizophrenia Trek

I became the owner of 7 seasons of TNG on DVD recently and noticed something. Season 2 Riker was posted to a Klingon vessel in an intergalactic officer exchange. On the Klingon vessel Riker learns &quot;A Klingon is his work not his family.&quot; Which flies in the face of the Worf son of Mog story line of latter TNG where Worf is struggling under the presumed shame that his father was a traitor. <div><br /></div><div>I</div><div>Anyone else ever notice &quot;Zebulon's Guide level&quot; of story inconsistency in trek?</div>
