Narrative/narration can also be a feature of a text otherwise technically defined as non-narrative: e.g., drama
Richard II:  narration of what King Henry said about Richard, from Exton’s perspective:
Exton. Didst thou not mark the king, what words he spake?
‘Have I no friend will rid me of this living fear?’
Was it not so?
Servant. These were his very words.
Exton. ‘Have I no friend?’ quoth he. He spake it twice,
And urged it twice together, did he not?
Servant.  He did.
Exton. And speaking it, he wishtly looked on me
As who should say, ‘I would those wert the man
That would divorce this terror from my heart.’
Meaning the king at Pomfret. Come, let’s go.
I am the king’s friend, and will rid his foe.    
(5.4.1-11)
