Ironic Ionic Italic in Dan Brown's Inferno and the Meaning Behind "behind"

I'm still in the process of reading Dan Brown's, Inferno, and I can't help butt get the sense that the inner twin world are behind this novel, as I discovered with his previous ones.  Regardless, I love his writing and so not actively looking for evidence of inner twin influence... butt then it just happened. 

On page 71 of Inferno, and three lines up from the bottom is a single word that stands out, "behind".  The only reason why it stands out is because it's in italics.  Why would Dan Brown put this word in italics, it didn't make sense... nott to me anyway?! 

This is the complete sentence: 

Several pedestrians did double takes as they passed, apparently puzzled to see a six-foot man in Brioni suit riding behind a slender woman. 

What stands out as well in the above, is the reference to "double takes"... anything having to do with "twin" and "double" are potential infiltration/leads of the inner twin world.   Bear in mind, that Dan Brown's Inferno was published by "DOUBLEDAY"!!  As well, the implication of "little woman" and "big man" in the sentence falls into pattern-clusters recently cropping up in a number of my posts.  The pattern-clusters are categorized into the following three titles: the "Little/Dwarf/Minney/Twig...", the   "Giant/Excess/Miles" and the "Opposites" (note: I've shortened the titles from previous posts). 

As to Dan Brown italicizing the word, behind, perhaps he did so to emphasize the irony of  a big strapping man taking the "back seat" to a little woman and not the other way around (as per societal "norm").  Personally, I use quotation marks around a word when I want to emphasize irony, butt then again I'm no expert.  So I decided to check it out, note the following from the "Quotation" wiki page http://en.wikipedia.org/wiki/Quotation_mark: 

Quotation marks can also be used to indicate a different meaning of a word or phrase than the one typically associated with it and are often used to express irony. 

 So now, note the following from the "Italics" wiki page https://en.wikipedia.org/wiki/Italic_type:

When to use : 

·         Emphasis: "Smith wasn't the only guilty party, it's true".

Okaay, so how audd is THAT?!   That the surname "Smith" is used in the example is astounding when  considering the "Smith" pattern-cluster that has occurred in the last couple of months!!

Since the word "only" was italicized in this example I decided to check out the etymology:

only (adj.) "only, unique, solitary," literally "one-like," from an "one" (see one) + -lic "-like" (see -ly (1)

It then dawned on me while on the topic of italics and the capital I, the text formatting section above that enables me to change the text to italics is represented by a capital/italicized I.  The prefix "itali" in the word "italicize" indicates an Italian origin... which is interesting because Dan Brown's Inferno is set in Italy.  Also interesting is that on the cover of the book, the letter "I" found in the title "Inferno", is emphasized in an artzy way-- it's flanked on either side with a filigree, making it appear more like a pillar, thte top and bottom of which scroll out with an "Ionic" order.

Hmmm, the ionic is usually only at the capital section (top/head) of the pillar.  This duality is further evidence of inner twin infiltration-- the "dual" capital/heads in "I"... or in other words-- the dual  "I" that exists in each of us.  Naturally our inner twin's consider themselves an "I" as we consider ourselves as "I"-- hence two "I's" in what appears to be a single body... as it should be.  Just as two eyes make for better vision (when precision lined), two "I's" make for thoughts (when precision lined).  The inner twin world's coming out and communicating to us at this point in time and in the manner they have chosen, is to better "align" our thoughts and thus actions.

Now that we know the inner twin are involved in Dan Brown's symbology, the question that comes to mind is, so what's the meaning behind "behind"?!  As to my Tou sense worth: Dan Brown's inner twin is definitely behind the ionic "I", AND the inner twin world are indicating that "they" are most definitely in the drivers seat despite our preconceived/misguided notions. 

There's definitely more to it, and as Robert Langdon puts it, Cerca Trova.
