The Winds Of Fate, CHAPTER THIRTEEN, pp. 173-202.
This long chapter opens:
"Galenos looked around the dinner table..." (p. 173)
At least for the time being, Galen is the pov character. The dinner conversation and Galen's thoughts impart information to the reader rather than advance the plot.
Near the top of p. 185:
"...Galenos thought."
He is still, consistently, the pov character. With dinner concluded and with those who do not "need to know" having withdrawn, Galen begins to convey a message from the Emperor to the three Americans who are present and to their single other confidante on the most important matter (time travel), Josephus. There is a double space between paragraphs...
After the space and with the message delivered, the leading American, Artorius/Arthur, not only slams his fist down but also sees that Galen is observing their reactions. Thus, the pov has shifted from Galen to Artorius. (I notice all this because I am a pov cop.)
The narrative must shift from imparting general information to delineating how the Americans respond to the devastating news that they are not the only time travellers in 170 CE and that is more than I can cope with this evening. Sorry to build up to a climax, then trickle to bed.
