Topic: style for internal dialogue, italics or not
So far, this is the best, more nuanced discussion:

Note that I gather the tone is: even if the italics for the purpose is around, it is unnecessary, and considering the Chicago Manual of Style does not include that method at all, it is understood that the style is not one that would be commonly accepted by readers or editors.
"Option #3, writing thoughts without italics, makes for the least intrusive read and is likely the best choice for most of today’s writers and for most genres. It may not be perfect for every story, genre, and set of circumstances, but it will work for many. Especially for stories with deep POV, that very intimate third-person point of view."
This my opinion: an italicized thought in the midst of a paragraph is intrusive and probably unnecessary. It can work but in low dosage, perhaps once in a chapter.
--- (quoting from above cited discussion)
The following is an example of thoughts without italics from a third-person POV. In this example, the reader is not being told Montrose’s thoughts, but actually hears them as Montrose thinks them.
{Montrose tilted his head to get a clearer view of the hoyden behind Giselle. They looked nothing alike, these two women posing as his dead wife’s sisters. He dismissed both with a flick of his wrist. They also looked nothing like his sweet, sweet Margaret.
(no italics) Stupid, ignorant fool. Should have known better than to believe. Than to hope . . .}
There is no doubt that Montrose is the one thinking these thoughts.
